    Question

    Five number-pairs are given, out of which three are

    alike in certain manner and one is different. Choose the different number-pair.
    A 18:108 Correct Answer Incorrect Answer
    B 25:150 Correct Answer Incorrect Answer
    C 30:210 Correct Answer Incorrect Answer
    D 40:330 Correct Answer Incorrect Answer
    E 60:540 Correct Answer Incorrect Answer

    Solution

    The second number is perfectly divisible by the first: (108 ÷ 18) = 6 (150 ÷ 25) = 6 (210 ÷ 30) = 7 (330 ÷ 40) leaves a remainder of 10. Option (d) does not follow the pattern. (540÷ 60) = 9
