‘A’ and ‘B’ invested Rs. 1200 and Rs. 1500 respectively to start a business. The ratio of the duration for which they kept their investments was 5:3, respectively. If the total profit generated was Rs. 2800, what is ‘A’s share of the profit?
Ratio of profit received by ‘A’ and ‘B’ = (1200 × 5):(1500 × 3) = 4:3 Profit share of ‘A’ = (4/7) × 2800 = Rs. 1600
