A and B together started a business with initial
investment in the ratio of 1:11, respectively. The time-period of investment for A and B is in the ratio of 3:7, respectively. Find the profit share of B, if the profit share of A is Rs 3000.Solution
Ratio of the profit share of A to B = (1 × 3): (11 × 7) = 3: 77 Profit share of B = (77/3) × 3000 = Rs 77000
