    Question

    The second number in the given number pairs is obtained

    by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs, except one. Find that odd number pair.
    A 4 : 68 Correct Answer Incorrect Answer
    B 6 : 220 Correct Answer Incorrect Answer
    C 8 : 510 Correct Answer Incorrect Answer
    D 9 : 733 Correct Answer Incorrect Answer

    Solution

    The pattern followed in these pairs is: Add '4' to the cube of the first number to get the second number. Option A: 4 : 68 → 4³ + 4 = 64 + 4 = 68. Option B: 6 : 220 → 6³ + 4 = 216 + 4 = 220. Option C: 8 : 510 → 8³ + 4 = 512 + 4 = 516 ≠ 510. Option D: 9 : 733 → 9³ + 4 = 729 + 4 = 733.
