Question
A and B started a business by investing Rs.7000 and
Rs.12000 respectively. After 4 months A withdrew 50% of his investment. If at the end of the year, profit share of B is Rs.7200, then find the profit share of A.Solution
Profit sharing ratio A and B = 7000 x 4 + 4500 x 8 : 12000 x 12 = 7:18 So, profit share of A = 7200 x (7/18) = Rs.2800
