the ratio of 3:5:7. After 8 months, A reduced his investment by one-third, while B doubled his investment. At the end of 12 months, the total profit earned was Rs. 73,500. Calculate the share of profit received by each friend.Solution
Let the invested money by A, B and C are 3x, 5x and 7x Ratio of their shares = 8×3x + 4×2x : 8×5x + 4×10x : 12×7x = 32x: 80x: 84x = 8: 20: 21 8y+20y+21y = 73,500 49y = 73,500 y = 1500 profit received by A, B and C = 8y, 20y, 21y = 12,000, 30,000, 31,500.
