Question

    The ratio of two numbers 'a' and 'b' is 6:2, respectively. Whereas the ratio of 'b' and 'c' is 10:11, respectively. When 14 is added to 'a', it becomes four times 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 '6k' and 2k respectively. So, 'c' = 2k X (11/10) = '2.2k' ATQ; (6k + 14) = 4 X (2k) Or, 6k + 14 = 8k Or, k = 7 So, required sum = 6k + 2k + 2.2k = 10.2 X 7 = 71.4
