Answer
Correct Answer: 88 : 16
Explanation
Introduction / Context:The rule appears to be “map a two-digit number to the sum of its digits”: 55 → 5 + 5 = 10. We must find another example matching this mapping.
Concept / Approach:Compute digit sums for each left-hand number and compare with the right-hand value.
Why Other Options Are Wrong:
- 15 : 5 — 1 + 5 = 6 ≠ 5.
- 18 : 1 — 1 + 8 = 9 ≠ 1.
- 16 : 75 — 1 + 6 = 7 ≠ 75.
- None of these — invalid since 8 + 8 = 16 matches.
Final Answer:88 : 16
