Question
A and B invested Rs.4000 each  in a business. AfterÂ
9 months , A withdrew 25%  of his capital and B added Rs.800 . If A gets Rs.2500  as his profit share at the end of the year, find B’s profit share.Solution
ATQ, Let the profit share of B = a (4000 * 9 + 4000 * (100 – 25)/100 * 3) / (4000 * 9 + (4000 + 800) * 3) = 2500/a (4000 * 9 + 3000 * 3) / (4000 * 9 + 4800 * 3) = 2500/a (36000 + 9000) / (36000 + 14400) = 2500/a 45000/50400 = 2500/a 25/28 = 2500/a 25a = 2500 * 28 a = (2500 * 28)/25 a = 2800 Therefore, the profit share of B = Rs.2800
