    C (47, 62, 40) Correct Answer Incorrect Answer
    D (91, 45, 32) Correct Answer Incorrect Answer

    Solution

    The logic followed here is: Product of both digits of the first number + Product of both digits of the second number = third number. (53, 16, 21) → (5 × 3) + (1 × 6) = (15 + 6) = 21   (82, 36, 34) → (8 × 2) + (3 × 6) = (16 + 18) = 34   (29, 83, 42) → (2 × 9) + (8 × 3) = (18 + 24) = 42   (47, 62, 40) → (4 × 7) + (6 × 2) = (28 + 12) = 40   (91, 45, 32) → (9 × 1) + (4 × 5) = (9 + 20) = 29 ≠ 32
