Quantitative Aptitude
Quantitative aptitude
forms a major section in Postal Assistant exam, so it shouldn't be taken
lightly and must be practiced on a regular basis.
Quantitative aptitude measures your overall
reasoning and analytical skills. It makes sure that you have the ability to
deal with practical issues and skills to achieve desirable success in life. A Quantitative
Aptitude test evaluates you on the numerical ability and accuracy level in the
mathematical calculations. It consists of several types of questions ranging from
pure numeric calculations to arithmetic reasoning.
First let’s delve into the challenges aspirants usually face at
Quantitative Ability.
Which
materials should I refer to? Are coaching materials enough?
I
have very low accuracy at this section? How do I increase my accuracy?
How
much time, do I should I spend on each question?
Students
are often under misconception that referring multiple materials will help them
in getting a better score. The idea is basically to get your fundamentals
strong. Initially, refer to one standard Book /material which is available in
the market. Once you are thorough with it, you can refer more materials just
for practice purpose. Ensure that no stone is left unturned when it comes to
coverage, as it is as important as depth.
A
good book: Buy a good book of quantitative Aptitude to improve your
basics. Most of the questions asked in these exams are of not more than 10th
class level. I suggest “Magical
Book on Quicker Maths – Tyra and Quantitative Aptitude by Arun Sharma.
The
syllabus of the Quantitative Aptitude is as follows.
Number
theory -
In Number theory, you will get questions on Divisibility, remainders, LCM and
HCF, MCQs on Unknown numbers from given condition for Fractions-comparisons.
Basic
Maths Questions - In basic math’s, you have to
prepare for Surds, indices, BODAMAS,
Roots, squares and Cubes.
Average
and Ratios: - In this section, you will get sub topic
questions like simple average, Ratio-Proportion-variations and questions on
partnership.
PERCENTAGE, PROFIT AND LOSS, RATIO AND
PROPORTION, PARTNERSHIP,CHAIN RULE, TIME AND WORK, PIPES AND CISTERNS, TIME AND
DISTANCE, PROBLEMS ON TRAINS, BOATS AND STREAMS, ALLIGATION OR MIXTURE, SIMPLE
INTEREST, COMPOUND INTEREST, AREA, VOLUME AND SURFACE
For
above sections, you need to practice a lot. Don't avoid above sections, as you
all know, above said topics are most asked question in competitive exam.
The Approach for Maths, stands
on two pillars.
Pillars
1.
Conceptual
Clarity : Read NCERT Books
For some topics directly from quantitative
aptitude books
2.
Lot of
Practice: From Quantitative aptitude books
Your
task is to cover one topic at a time, first get conceptual-clarity and then
solve maximum questions at home.
The very first step to
prepare well for quantitative aptitude is to know well about the types of
questions that are covered under this heading. This can be done by a little bit
of research and by taking up the questions of this section.
Once you know about the types of questions, one by one take up these types and start preparing. When you start preparing for a question type, take up as many questions as you can from good books and papers and try solving them. Do not consider any type less important or insignificant because you never know which question type may be highlighted in this section.
Whenever you learn any short-cut technique, you note it down in your diary. Similarly, whenever you make any mistake while solving sums, you also note that down in your diary. Night before the exam, you review that diary of mistakes. Why do this? Because it is the “Art of Aptitude.

Whenever you learn any short-cut technique, you note it down in your diary. Similarly, whenever you make any mistake while solving sums, you also note that down in your diary. Night before the exam, you review that diary of mistakes. Why do this? Because it is the “Art of Aptitude.
Merely
knowing the concepts or formulas won’t help. Because unless you practice
different variety of questions, you won’t become proficient in applying those
concepts flawlessly in the actual-exam.
Second,
despite knowing concept and formulas, people make silly mistakes either in
calculation or in plugging the values.
Make
sure you learn how to recognize when/ why should use a specific method to solve
a problem. Work on practice problems for each topic ranging in levels of difficulty.
When practicing, try to solve the problem on your own first then look at the
answer or seek help if you are having trouble.
Questions in
quantitative aptitude are not very tough; the only thing needed is practice so
that you'll realize how to manage time by Switching between
questions by leaving time taking questions for the end.
By firm practice,
you'll get good at switching between questions and save time which is
the deciding factor in such exams.
Also, if you are
unable to solve a few questions do make it a point to get it solved from a
senior, teacher or a fellow student. Don't leave any question unsolved.
Once you get in a
habit of attempting these questions start focusing on your accuracy. Though it
is important to attempt all questions it is equally important to do them
accurately. After you've worked
on achieving a high accuracy level, you need to learn the technique of time
management because it is important to attempt the questions correctly in a
given amount of time. You cannot just sit for hours solving one question. This
again can be achieved by a lot of practice.
If
you simply cannot determine the answer to a question, make a guess. Think
about the problem and the information you know to be true. Make a guess
that will be logical based upon the conditions of the problem. After you
perform your calculations, see if your final answer is close to your guess.
Important Tips:-
1. Learn shortcuts- Formula and tricks
The first step is to learn all basic formulae, the most important
being the rule of BODMAS, this will allow you to solve simple mathematical
questions. Then try to learn various tricks to solve a quantitative aptitude
problem. For instance, tricks such as learning where addition or multiplication
is to be used can help. The best way to learn tips and tricks is to follow
logical thinking and attitude.
Basic
Calculations: Practice basic calculations involving addition, subtraction,
multiplication, division, percentage increase, fractions etc on daily basis. I
know it sounds silly for a pro (in school time) in Mathematics but it is a
necessary thing to do to improve your score.
2. Learn to estimate the answers and use of Common sense
Believe it or not!
Common sense is the most important tool when it comes to solving quantitative
aptitude problems. So, use common sense. Think what could be more practical and
then choose your solution. Have
a fair clarity on how to get the right option in minimal time.
3. Learn to do mental calculations
Numerical
Ability section is designed to make you rely on quicker mental calculations
otherwise its hard to get a very good score. The less paper you use for
calculations, the better you could score.
4. Time management
Generally, students spend too much of time for solving a single
quantitative aptitude question. And although they end with the correct answer,
they might not be able to complete all questions. Therefore, divide time.
Ideally, nothing more than two minutes should be given to a quantitative
aptitude question.
5. Practice makes a man perfect
Yes! Practice is the key. Don’t expect yourself to be too
intelligent, rather hone your skills by practicing mock tests. These tests will
give you a fair idea about what type of questions may come and also allow you
to find the best ways to produce the right answer. Moreover, practicing tests
gives you an opportunity to learn time management and reduces average time for
getting a solution.
6. Make friends
Well, if you are actually interested in clearing the quantitative
aptitude test with flying colours, then you should practice by making friends.
Friends, who have common goals, can help you in studying and finding different
ways of getting a solution. Moreover, you can do mock tests and ask each other
questions, discuss on the techniques used for deriving an answer.
7. Sleep and exercise
Finally, it is important to treat your body well if you want to
enhance your capabilities. Therefore, sleep at least 8 hours a day to make sure
that your brain has enough time to rest. Also, start exercising. This will not
just keep you fit on physical levels, but it will also make sure that your mind
exercises and receive better blood flow to protect your memory.
At the time of Examination
(Quantitative Part)
The
Aspirant must not lose the confidence during preparation and while giving the
examination.
One
should be able to attempt easy questions successfully in reasonably quick time,
and he should also be able to attempt most of the moderate level questions. One
should ensure that not much time is spent trying difficult questions that you
cannot understand. The mantra is to allocate one minute of thinking time for
each difficult question. If you feel you have not made any headway, jump to the
next question. This will ensure that you don’t up end wasting time too much
time on a single question. If you have time left at the end of the test, you
can always come back to answer the remaining questions.
Don't
panic if you can't solve the question. Just move on & try to solve another
one.
If
time permits, go back and resolve the more difficult problems on the test on a
separate piece of paper. If these "new" answers are the same as
your previous answers, chances are good that your solution is correct.
Do
not feel that you must use every number in a problem when doing your
calculations. Some mathematics problems have "extra"
information. These questions are testing your ability to recognize the
needed information, as well as your mathematical skills.
If
you know that your answer to a question is incorrect, and you cannot find your
mistake, start over on a clean piece of paper. Often times when you try to
correct a problem, you continually overlook the mistake. Starting over on
a clean piece of paper will let you focus on the question, not on trying to
find the error.
Whenever
possible, draw a diagram. Even though you may be able to visualize the
situation mentally, a hand drawn diagram will allow you to label the picture,
to add auxiliary lines, and to view the situation from different perspectives.
Always
read math problems completely before beginning any calculations. If you
"glance" too quickly at a problem, you may misunderstand what really
needs to be done to complete the problem.
Reasoning Preparation
Reasoning is
getting much attention in most of competitive
exams to test the judgement and other skills related to presence
of mind and analytical ability of a candidate.
Reasoning can be
taken as a scoring subject as compared to the quantitative section as
it takes only thinking ability of a candidate and if the candidate is able to
apply it, in most cases he can be sure of his scoring.
Reasoning
questions are very important part as they test candidate's decision
making, preciseness, analytical ability etc. Reasoning questions
are normally considered to be very confusing as the candidates cannot
easily decide on an answer without taking some time and applying good
analytical skills so reasoning should not be attempted first. Candidate should
attempt this section after saving some time from Questions of General awareness
and General English.
Reasoning mostly
covers sections like Critical Reasoning, Analytical reasoning and
Reasoning Data Sufficiency. Reasoning basically depends on the skill level and
thinking ability of mind and if the candidate lacks in that, he needs to
develop them through hard practice of reasoning questions.
Reasoning
questions have large variety and widely classified into verbal and
Non-verbal reasoning.
Verbal reasoning includes questions
classified as below:-
Alphabetical and numerical series
Questions deriving from some given
facts and relations
Questions on Directional analysis
Coding-decoding on a pattern
Questions on age calculation
Questions on Mirror images
Questions on Human relations
and More.......
Non-verbal
reasoning includes questions on some series of graphical representations.
For example, four graphical pictures are shown depending upon some series; the
candidate has to decide the next in series by finding out the logic used in
creating the series.
Topics to be prepared
Series
Analogy (both word based and
numerical)
Odd pair (both word based and
numerical)
English Dictionary based
word arrangements, missing letters
Box containing some number,
you’ve to find missing number.
Ranking, missing characters
etc
As
you can see from the above, majority of the questions are asked from “series”
(analogy, odd pairs, dictionary etc). Around half of the reasoning questions
are based on this topic only.
Therefore,
I suggest you first solve all the sums related to “series” from your reasoning
book. And within that, more emphasis should be given to
Analogy
(words and numbers)
odd
pair (same)
Classification
Dictionary
based series
Inserting
missing characters
Logical
sequence of words
The
word based analogy/odd pair is very easy (compared to number based or letter
based).
But
number based analogy/odd pair etc. can be a tough cookie.
So
while in exam, keep an eye on wrist watch. Don’t spend too much time in just
one question.
Coding and Decoding
Typical coding decoding
(PEAR written as GFDN then REAP is written as..)
Symbols (circle is greater
than, square is less than.
Maths operations (L=x, M=+,
then value of 16L12M13 is.
Math
operation. Can be mastered with practice and can be solved quickly and
accurately. Same for symbol.
So
practice as much as you can.
Conventional
Venn diagram questions. (50 drink coffee, 40 drink tea…) Usually just 2
questions come. Good part, answer can be verified and once you practice enough
it doesn’t even take one minute to solve it (2 circle venn diagram cases).
Arrangement
Sitting arrangement (line,
table and circular)
Blood relations
(mom-dad-father in law)
Building, car, colour,
occupations of persons.
Schedules (lecture on
Monday..etc.)
Direction based (Mohan moves
three kms north…how far he is from home
To
a new player, the arrangement questions may appear time-consuming. But once
you’ve practiced enough sums, your speed will improve.
But
the best thing with arrangement question, you can verify the answer (by
applying the “conditions” given in the question to your arrangement).
Easiest
of all arrangement is circular arrangement. Solve each and every sum given in
your book. Once you’re comfortable with circular, move to linear and
rectangular (dining table).
Next
comes, Direction based question. Solve each and every sum given in your book.
Finally
blood relations.
Misc.
Clock, calendar
Permutation Combination (rare)
Age related problems (dad
is 22 older than..)
Geometry
Image based
(non-verbal)
Cubes-dices: predicting color,
numbers in other faces
Sequence of figures
Paper-cutting, folding,
punching
Mirrors and water reflection
Configuration, fitting pieces,
odd pieces etc
Here are some tips to develop reasoning skills and
solve reasoning problems.
Practice Puzzles-
Solving puzzles can greatly help in improving solving skills and thereby helps
to improve your reasoning power.
Analyse and
arrange- Try to analyse what is given in the question and note it in
a proper way on a paper to help you solve better.
Work on Given
Data- Remember that the given problem will be solved by the data
given only, don’t make any assumptions or judgment while solving the
question.
Negative
prefixes- Be careful with words having negative prefixes like un-, non- , they
can fool you for facts.
Use elimination-
If nothing is coming out as a conclusion; try eliminating options according to
the information given to find the correct answers.
Eliminate all words that are irrelevant to the argument.
Even though you need to comprehend all the words in the stimulus, they're not all important. The only words you'll need to deal with are the ones that make up the evidence and conclusion.
DONOT assume, USE ONLY Info provided in the question. This important as we need to unlearn the info we generally have and use on the info provided.MAKE SURE you have read all the choices carefully before proceeding to answer. NOTICE: The special clues, like “all,” “some,” or “none” when you read the factual information given in the question. Other qualifying words such as “other than,” “only” or “unless” are important, too. These cues can play a critical part in specifying the facts to be used in your reasoning.
Pay
more attention to the word like “ONLY” and to the phrase “IF AND ONLY IF.”
Saying “The Box will open IF AND ONLY IF both keys are used” sets up a highly
specific condition that must be met. There is exactly one way to open the
door-you must use both keys. By contrast, if the sentence says, “The Box will
open if the key is used,” there may be several ways to open the door besides by
using the key.
In
questions that ask you to select a valid conclusion, always choose the one
conclusion that must definitely follow from the information you are given. In
questions that ask you to find the invalid alternative, choose the one
conclusion that does not definitely follow from the information.
It is good idea to use the
paper to draw the matrix, Venn diagram or schema to solve the logical
reasoning questions.
Try
to solve the easier questions first that can be concluded easily with
the first hand information form the passage or the question. You can
come back to difficult question again, this help to save time and score more marks.
English Preparation
By
this competitive exam, the Department weighs the abilities of a candidate such
as subject knowledge, reasoning abilities, conceptual knowledge, English
Grammar, memory power, English sentence making skills etc. Competition is
placed among the candidates is not only weighs the aspirants abilities but also
help the Department to eliminate them who are not perfect for vacant seats.
Thus the candidates have to face much tough competition in order to recruit for
jobs.
Recommended
Book for English Grammar
Some
people might even advise you to use “Wren & Martin” etc. but such books are
written from board exams/ academic point of view. And for the competitive exams
we don’t need to study everything of English grammar; we just need a set of
rules and practice questions.
If
you already have some English grammar book (R.S.Agarwal, A.P.Bhardwaj) etc. use
it.
If
you don’t have any book, I suggest you go for Objective General English by
SP Bakshi (Arihant Publication)
He
has given direct “rules” and example-sentences from competitive exam point of
view and it makes easy to handle sentence correction.
Plus,
the book also contains good list of phrasal verbs, idioms and vocabulary
The
Postal Assistant exam includes the general English questions such as
on the topics of:
Grammar
Vocabulary
Sentence completion
Synonyms & Antonyms
Comprehension of a passage
Spotting the Errors
Filling in the blanks
Use of prepositions, idioms/phrases, Articles
Test of spellings
Re-arranging jumbled up sentences, etc.
Tenses Active and Passive Voice and
Transformation
Direct and Indirect Speech
The
level of questionings come in the exams is of 10th or 12th standard
questions.
A
candidate must have to prepare for the above mentioned topics in English to
score a good percentage. The candidate can increase their English properly by
reading English grammar books.
Question will be
asked from Vocabulary which include Antonym, Synonym, Idioms,
spelling check, fill in the blanks, idioms etc , English
Grammar and Comprehension, which include a unseen passage, Error correction,
sentence improvement. There is no hard and fast rule, how many questions will
come from a specific topic
For Vocabulary:
Word Power Made Easy by Norman Lewis
Read Word
Power Made Easy by Norman Lewis , This book
is a real gem, if you don't have this, then you must purchase it,
because this book will tell you about origin of words and you will hardly
forget the words learnt from this book.
Remember Cramming
will not help you anyway in Vocabulary. You will have to understand the meaning
of the words. Moreover many times directly question come from this book. This
book many times helps you guess the meaning of the words, even if you see the
word for the first time.
Practice from
practice exercise at-least 2-3 times and mark words you forgot
with red pen. Next time your attention will be there and you will remember
that word forever.
Make a habit of
reading English newspaper like THE HINDU or Indian Express and take a big notebook
and write down meaning of new words (Use Dictionary or Online) you
come across while reading.
Don't forget to
revise your notebook and use them in your conversation and make memory link up
with words you know. It depends on you, how you link up your memory to recall.
The notebook
should be with you with constant updates until you clear some exam of your
choice.
Moving
to the next topic:
Grammar
rules
From
your grammar books, Study the grammar rules of noun, pronoun, adjective,
adverb, verb, conjugation, articles, active-passive, direct-indirect,
parallelism, embedded question, with examples for sentence correction.
Solve
maximum number of questions from standard book. If you come across any unique
rule/case for sentence correction, note it in your diary for future reference.
English
Grammar: Approach
1.
Active Passive (voice) and Direct-Indirect (speech)
This
is no-excuse topic. Because it relies on a set of simple rules, almost like
math formulas.
Understand
the grammar rules and practice maximum questions.
In
your “diary” note down any special/odd rules you come across- including example
sentences.
2.
Sentence Correction& Improvement
To
master sentence correction, you’ve to master two subtopics:
Grammar
rules, Phrasal verbs
A.
Grammar Rules
First
of all you need to know the grammar rules. But you don’t need to know all
grammar rules.
Because
in competitive exam, sentence correction relies on certain specific mistakes
only.
For
example: The topic “verb” has lot of theory and classifications.
But
for “sentence correction”, it boils down to very few rules for example
Either,
Neither, none, each and every is singular.
Wrong Each of the Solders are
disciplined
Right Each of the Solders is disciplined
Your
task, first go through your grammar book, and note down such rules with example
statements, in your note book. Revise these rules often (along with example
sentences).
B.
Phrasal Verbs
Grammar
rules are like maths. Universal valid.
But
Phrasal verbs are different game altogether. You need to know memorize the
correct usage- case to case basis. For example:
Correct
Phrasal verb wrong
usage
Dispose
of = sell He has decided to
dispose off his property
Dispose
to = willing, interested He is
disposed in discussing that business proposition
Both
statements are wrong because phrasal verbs are incorrectly used.
Many
a times, candidates know the grammar rules very well, but they fail to detect
the error in sentence because they’ve not prepared the phrasal verbs.
You
next task: revise the list often and write down the very confusing ones into
your diary: with example sentence. Once this is done, try to solve as many
practice questions as you can.
3.
Comprehension + Sentence Arrangement
Just
one word: Practice.
Read English
Newspaper daily, it will help sharpen your reading skills, fast and effective
reading is necessary for any competitive exams otherwise your time will be
over.
So make a habit
of fast reading. Normally, first few lines of the passage, give you idea, what
author is talking about. So, pay greater attention to first few lines.
Whenever
you solve comprehension passages at home or read any English
book/newspaper/web-article, you should note down any unfamiliar words in a
separate diary.
Revise
this diary once in a while. Don’t stop this exercise after the exam is over.
Continue it, until you’re selected in your dream job.
SUMMARY
The Days left
for the exams should have a scheduled time table prepared by the candidate for
preparation. After making the schedule just stick to it. The time table must
have all the required routine in preparation time mentioned. Also must include
the timings of the resting and exam preparation, and other important activities.
Take some rest time in the schedule too, so your mind will keep fresh, and
don’t take much stress while preparations this may affect the health and mind
both. Keep the self-confidence, do hard work, keep well time management. By
doing this all you will be tough to compete in the examination.
The
candidate must have a confidence and a self-belief always when he/she appearing
for the exam, just believe your own abilities. Hard work with knowledge will
take you a step forward to the success. Try to attempt Sample
papers and solved previous years papers so you can find where
you are lacking. Try to keep a watch behind or a stop watch to check your own
speed of attempting the questions. To score well in the examinations try some
tricks to remember the big formulas with key that recall it easily.
That's all
for now friends. Happy Reading
- Akula.
