    Three of the following four options are alike in a

    certain way and thus form a group. Which is the option that does NOT belong to that group? (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
    A 4 - 2 - 72 Correct Answer Incorrect Answer
    B 5 - 3 - 152 Correct Answer Incorrect Answer
    C 2 - 6 - 210 Correct Answer Incorrect Answer
    D 3 - 4 - 91 Correct Answer Incorrect Answer

    Solution

    The sum of the cubes of the first and second numbers equals the third number. Option A: '4 - 2 - 72' → 4³ + 2³ = 64 + 8 = 72 Option B: '5 - 3 – 152’ → 5³ + 3³ = 125 + 27 = 152 Option C: '2 - 6 - 210' → 2³ + 6³ = 8 + 216 = 224 ≠ 210 Option D: '3 - 4 - 11'→ 3³ + 4³ = 27 + 64 = 91
