A, B and C are partners in a business. A, whose capital has been used for 5 months, claims 1/7 of the profit. B whose capital has been used for 7 months, claims 1/5 of the profit. C has invested Rs. 4,600 for 9 months. How much capital did A contribute? Correct Answer Rs. 1,800
Let the total profit be 35 unit.
Profit of A = 1/7 × 35 = 5 unit
Profit of B = 1/5 × 35 = 7 unit
Profit of C = 35 – 5 – 7 = 23 unit
Let the capital of A and B are x and y, respectively.
As we know,
Capital × Time = Profit
5x : 7y ∶ 4600 × 9 = 5 : 7 : 23
According to the question
5x/(4600 × 9) = 5/23
x = 9 × 200 = 1800
So, A contribute Rs. 1800
