1. Partnership: When two or more than two persons run a business jointly, they are called partners and the deal is known as partnership.

Partnership is an association of two or more persons who invest their money in order to carry on a certain business. a partner who manages the business is called working partner and the partner who simply invests is called the sleeping partner.

If the period of investment is same for each partner, then the profit or loss is divided in the ratio of their investments.

The simple formula involved is (if there are two partners A and B)
Investment of A x period of investment of A = profit /loss of A
Investment of B x period of investment of B profit /loss of B
OR,
Monthly equivalent investment of A= profit /loss of A
Monthly equivalent investment of B profit /loss of B

2. Ratio of Division of Gains:

     i) When investments of all the partners are for the same time, the gain or loss is distributed among the partners in the ratio of their investments.

Suppose A and B invest Rs. x and Rs. y respectively for a year in a business, then at the end of the year:

(A’s share of profit) : (B's share of profit) = x : y.

     ii) When investments are for different time periods, then equivalent capitals are calculated for a    unit of time by taking (capital x number of units of time). Now, gain or loss is divided in the ratio of these capitals.

Suppose A invests Rs. x for p months and B invests Rs. y for q months, then

 (A’s share of profit) : (B's share of profit) = xp : yq.

3. Working and Sleeping Partners: A partner who manages the business is known as a working partner and the one who simply invests the money is a sleeping partner.


                                   EXAMPLES

 1. A, B and C started a business by investing Rs. 1,20,000, Rs. 1,35,000 and ,Rs.1,50,000 respectively. Find the share of each, out of an annual profit of Rs. 56,700.

Sol. Ratio of shares of A, Band C = Ratio of their investments

= 120000 : 135000 : 150000 = 8 : 9 : 10.
A’s share = Rs. (56700 x (8/27))= Rs. 16800.
B's share = Rs. ( 56700 x (9/27)) = Rs. 18900.
C's share = Rs. ( 56700 x (10/27))=Rs. 21000.

2. Alfred started a business investing Rs. 45,000. After 3 months, Peter joined him with a capital of Rs. 60,000. After another 6 months, Ronald joined them with a capital of Rs. 90,000. At the end of the year, they made a profit of Rs. 16,500. Find the lire of each.

 Sol. Clearly, Alfred invested his capital for 12 months, Peter for 9 months and Ronald
         for 3 months.

         So, ratio of their capitals = (45000 x 12) : (60000 x 9) : (90000 x 3)

                                             = 540000 : 540000 : 270000 = 2 : 2 : 1.
         Alfred's share = Rs. (16500 x (2/5)) = Rs. 6600
         Peter's share = Rs. (16500 x (2/5)) = Rs. 6600
         Ronald's share = Rs. (16500 x (1/5)= Rs. 3300.

 3. A, Band C start a business each investing Rs. 20,000. After 5 months A withdrew Rs.6000, B withdrew Rs. 4000 and C invests Rs. 6000 more. At the end of the year, a total profit of Rs. 69,900 was recorded. Find the share of each.

Sol. Ratio of the capitals of A, Band C

                     = 20000 x 5 + 15000 x 7 : 20000 x 5 + 16000 x 7 : 20000 x 5 + 26000 x 7

                      = 205000:212000 : 282000 = 205 : 212 : 282.

         A’s share = Rs. 69900 x (205/699) = Rs. 20500                        I
                                                                                                            
        B's share = Rs. 69900 x (212/699) = Rs. 21200;

        C's share = Rs. 69900 x (282/699) = Rs. 28200.
                                                    
 4. A, Band C enter into partnership. A invests 3 times as much as Band B invests two-third of what C invests. At the end of the year, the profit earned is Rs. 6600. What is the share of B?

Sol. Let C's capital = Rs. x. Then, B's capital = Rs. (2/3)x
        A’s capital = Rs. (3 x (2/3).x) = Rs. 2x.
      Ratio of their capitals = 2x : (2/3)x :x = 6 : 2 : 3.
     Hence, B's share = Rs. ( 6600 x (2/11))= Rs. 1200.

5. Four milkmen rented a pasture. A grazed 24 cows for 3 months; B 10 for  5 months; C 35 cows for 4 months and D 21 cows for 3 months. If A's share of rent is Rs. 720, find the total rent of the field.

Sol. Ratio of shares of A, B, C, D = (24 x 3) : (10 x 5) : (35 x 4) : (21 x 3)   = 72 : 50 : 140 : 63.
                                                                                  
               Let total rent be Rs. x. Then, A’s share = Rs. (72x)/325

                      (72x)/325=720 ó x=(720 x 325)/72 = 3250   
              
              Hence, total rent of the field is Rs. 3250.
              
6. A invested Rs. 76,000 in a business. After few months, B joined him Rs. 57,000. At the end of the year, the total profit was divided between them in ratio  2 : 1. After bow many months did B join?

Sol. Suppose B joined after x months. Then, B's money was invested for (12 - x)

                     (76000 x 12)/(57000 x (12-x) =2/1 ó 912000=114000(12-x)
                                               
 114 (12 - x) = 912ó12-x=8óx=4

 Hence, B joined after 4 months.

7. Three partners A, B and C invest Rs 1600, Rs 1800 and Rs 2300 respectively in a business. How should they divide a profit of Rs 399?

sol: here profit is to divided in the ratio 16:18:23

A's share of profit=16/(16+18+23)x 399= Rs 112.
B's share of profit=18/(16+18+23)x 399= Rs 126
C's share of profit=23/(16+18+23)x 399= Rs 161

8..A. B and C enter into a partnership. A advances Rs 1200 for 4 months. B gives Rs 1400 for 8 months and C Rs 1000 for 10 months. they gain Rs 585 altogether. find the share of profit each?

sol: monthly equivalent of A = 1200 x 4= 4800
Monthly equivalent of B = 1400 x 8= 11200
Monthly equivalent of C = 1000 x 10= 10000
So, profit is to be divided in the ratio 48:112:100 i.e. 12:28:25
A's share of profit is (12/65)x 585=Rs108
B's share of profit is (28/65)x 585=Rs252
C's share of profit is (25/65)x 585=Rs225
9. Simran started a software business by investing Rs. 50,000. After six months, Nanda joined her with a capital of Rs. 80,000. After 3 years, they earned a profit of Rs. 24,500. What was Simran's share in the profit?
Sol:  Simran : Nanda = (50000 x 36) : (80000 x 30) = 3 : 4.

A : B = 3 : 2

 B : A = 2 : 3 = 4 : 6 and A : C = 2 : 1 = 6 : 3.




So, B : A : C = 4 : 6 : 3 or A : B : C = 6 : 4 : 3.



B's share = Rs.

157300 x

 = Rs. 48400.
33.A and B started a business jointly. A’s investment was thrice the investment of B and the period of his investment was two times the period of investment of B. If B received Rs. 4000 as profit, then their total profit is:
Suppose B invested Rs. x for y months. Then, A invested Rs. 3x for 2y months.

So, A : B = (3x x 2y) : (y) = 6xy = 6 ; 1.



B’s proft : Total profit = 1 : 7.


Let the total profit be Rs. x. Then,
1

 or x = 28000.
34. A, B and C enter into partnership. A invests some money at the beginning, B invests double the amount after 6 months and C invests thrice the amount after 8 months. If the annual profit be Rs. 27,000, C’s share is :

Let A's investment be Rs. x.

Then, Ratio of capitals = (x x 12) : (2x x 6) : (3x x 4) = 12x : 12x : 12x = 1 : 1 : 1.



C's share = Rs.

 = Rs. 9000.
35.A, B and C started a shop by investing Rs. 27,000, Rs. 72,000 and Rs. 81,000 respectively. At the end of the year, the profits were distributed among them. If C’s share of profit be Rs. 36,000, then the total profit was:
A : B : C = 27000 : 72000 : 81000 = 3 : 8 : 9. So, C's share : Total Profit = 9 : 20.

Let the total profit be Rs. x. Then,
9

Thus, B’s money was used for 10 months.
37. A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A’s share is Rs. 855, the total profit is :

Let the total profit be Rs. 100

After paying to charity, A’s share = Rs.

95 x

57
 x 855

 =1500.
38. A, B, C started a business with their investments in the ratio 1 : 3 : 5, After 4 months, A invested the same amount as before and B as well as C withdraw half of their investments. The ratio of their profits at the end of the year is :

Let their initial investments be x, 3x and 5x respectively. Then

A : B : C = (x x 4 + 2x x 8) :

3x x 4 +

39.Simran started a software business by investing Rs. 50,000. After six months, Nanda joined her with a capital of Rs. 80, 000. After 3 years, they earned a profit of Rs. 24, 500. What was Simran’s share in the profit?

Simran : Nanda = (50000 x 36) : (80000 x 30) = 3 : 4.


 Simran's share = Rs.

24500 x

 = Rs. 10500.
40.A and B started a business with initial investments in the ratio 14 : 15 and their annual profits were in the ratio 7 : 6. If A invested the money for 10 months, for how many months did B invest his money?

Suppose A invested Rs. 14x for months and B invested Rs. 15x for y months. Then,

14x x 10
15x x y
 =

 = 8.


Hence, B invested the money for 8 months.

41. A, B, C hired a car for Rs. 520 and used it for 7, 8 and 11 hours respectively. Hire charges paid by B were :

A : B : C = 7 : 8 : 11.

Hire charges paid by B = Rs.

520 x

 = Rs. 160.
42. A, B and C enter into a partnership with a capital in which A’s contribution is Rs. 10,000. If out of a total profit of Rs. 1000, A gets Rs.500 and B gets Rs. 300, then C’s capital is:
A : B : C = 500 : 300 : 200 = 5 : 3 : 2.

Let their capitals be 5x, 3x, 2x respectively.

Then, 5x = 10000

  x = 2000.




C's capital = 2x = Rs. 4000.


43.Reena and shaloo are partners in a business. Reena invests Rs. 35,000 for 8months and shaloo invests Rs. 42,000 for 10 months. Out of a profit of Rs. 31,570, Reena’s share is:
Ratio of their shares = (35000 x 8) : (42000 x 10) = 2 : 3.

Reena's share = Rs.

31570 x

 = Rs. 12628.
44.A starts business with Rs. 3500 and after 5 months, B joins with A as his partner. After a year, the profit is divided in the ratio 2 : 3. What is B’s contribution in the capital?


Let B's capital be Rs. x. Then.
3500 x 12
7x
=

14x = 126000

 = 9000.


45. Three partners A, B, C start business. Twice A’s capital is equal to thrice B’s capital and B’s capital is four times C’s capital. Out of a total profit of Rs. 16,500 at the end of the year. B’s share is :

Let C = x. Then, B = 4x and 2A = 3 x 4x = 12x or A = 6x



A : B : C = 6x : 4x : x = 6 : 4 : 1



So B's capital = Rs.

16500 x
4
 /11
 = Rs. 6000.
46.A started a business with Rs. 21,000 and is joined afterwards by B with Rs. 36,000. After how many months did B join if the profits at the end of the year are divided equally?

Suppose B joined after x months

Then, 21000 x 12 = 36000 x (12 – x)

36x = 180

 x = 5.
