    Question

    The ratio of two numbers 'a' and 'b' is 7:4,

    respectively. Whereas the ratio of 'b' and 'c' is 5:8, respectively. When 15 is added to 'a', it becomes thrice of 'b'. Find the sum of 'a', 'b' and 'c'.
    A 55.66 Correct Answer Incorrect Answer
    B 52.2 Correct Answer Incorrect Answer
    C 65.5 Correct Answer Incorrect Answer
    D 75.2 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, let the numbers 'a' and 'b' be '14k' and 8k respectively. So, 'c' = 8k X (8/5) = '12.8k' ATQ; (14k + 15) = 3 X (8k) Or, 14k + 15 = 24k Or, k = 1.5 So, required sum = 14k + 8k + 12.8k = 34.8 X 1.5 = 52.2
