    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?
    A 1:3:4 Correct Answer Incorrect Answer
    B 7:9:11 Correct Answer Incorrect Answer
    C 8:9:12 Correct Answer Incorrect Answer
    D 2:3:11 Correct Answer Incorrect Answer

    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.
