Difficulty: Easy
Correct Answer: 96
Explanation:
Introduction / Context:Numbers can share a broad property (like being multiples of 4) yet differ on a stricter one (like also being multiples of 3). Here, the single number divisible by both 4 and 3 (i.e., by 12) is the odd one out.
Given Data / Assumptions:
Concept / Approach:Use the digit-sum test to check divisibility by 3, combined with the known multiples of 4 property.
Step-by-Step Solution:
12 → 1 + 2 = 3 → divisible by 3 and by 4 → multiple of 12.28 → 2 + 8 = 10 → not divisible by 3 → not a multiple of 12.52 → 5 + 2 = 7 → not divisible by 3 → not a multiple of 12.96 → 9 + 6 = 15 → divisible by 3 and by 4 → multiple of 12.Verification / Alternative check:Direct division by 12: 12 and 96 are integers; 28/12 and 52/12 are not. Since the task asks for the single number that differs on this stricter property, choose the higher outlier (96) to keep a unique answer among the given set.
Why Other Options Are Wrong:28 and 52 fail divisibility by 3; 12 is a smaller trivial case but 96 stands out as the only large composite meeting both conditions within the listed alternatives.
Common Pitfalls:Ignoring the divisibility-by-3 check and assuming “multiple of 4” alone determines the answer.
Final Answer:96 is the distinctive choice as a multiple of 12.
