Question
A and B started a business with investments in the ratio
5:4 respectively. After 4 months, C joined them with an investment 30% more than the investment of B. Find the profit share of C out of the total profit of Rs 3200 at the end of two yearsSolution
Let the investments of A and B be Rs. 5x and Rs. 4x respectively. So, the investment of C = 1.30 × 4x = Rs. 5.2 x So, the ratio of their investments = (5x × 24): (4x × 24): (5.2x × 20) = 15:12:13 So, the profit share of C = 15/40 × 3200 = Rs. 1040
