    If 'M' is the square root of the nearest square to the

    wrong number in following series, then find the value of '2M'. 64, 12, 88, 15, 110, 17.625
    A 12 Correct Answer Incorrect Answer
    B 18 Correct Answer Incorrect Answer
    C 26 Correct Answer Incorrect Answer
    D 22 Correct Answer Incorrect Answer
    E 20 Correct Answer Incorrect Answer

    Solution

    64 x (1/8) + 4 = 12

    12 x 7 + 4 = 88

    88 x (1/8) + 4 = 15

    15 x 7 + 4 = 109

    109 x (1/8) + 4 = 17.625

    Therefore, 109 should come in place of 110

    So, the nearest square is 100

    So, M = 10

    Or, 2 x M = 20
