their time periods is 3 : 2 : 7 respectively. Ratio of the profits of A, B and C is 4 : 3 : 14 respectively. What is the ratio of the investments of A, B and C?Solution
Let time periods investments be T1, T2, T3 The ratio of investments is A, B, and C = 3: 2: 7 The profits in the ratio = 4: 3: 14 Time period T1, T2, T3 = p1/x1: p2/x2: p3/x3 ⇒ T1,T2, and T3 = 4/3, 3/2, 14/7 ⇒ T1 ∶ T2 ∶ T3 = 8 ∶ 9 ∶ 12 ∴ Ratio of investment is 8 ∶ 9 ∶ 12.
