Show answer & explanation

Correct answer: D

In an analogy of the form A : B :: C : ?, the same transformation that turns A into B must be applied to C to find the missing term. Here that transformation is a uniform digit-wise reduction — every digit of the first number is reduced by a fixed amount to give the second number.

  1. Compare 985 and 874 digit by digit: 9 → 8, 8 → 7, 5 → 4. Every digit has been reduced by exactly 1.

  2. Apply the same digit-wise reduction to 763: 7 → 6, 6 → 5, 3 → 2.

  3. Combining the reduced digits gives 652, the value that fits the identified pattern.

Cross-check: adding 1 back to each digit of 652 (6+1=7, 5+1=6, 2+1=3) restores 763, confirming the same rule holds consistently for both pairs.

Hence, 763 : 652 completes the analogy, matching the pattern set by 985 : 874.
