Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:Divisibility by 4 can be checked using the last two digits. The outlier fails this test. Given Data / Assumptions: Set: 64, 208, 316, 118. Rule: A number is divisible by 4 if its last two digits form a number divisible by 4. Concept / Approach:Inspect the last two digits and apply the rule quickly. Step-by-Step Solution: 64 → last two digits 64 → divisible by 4.208 → last two digits 08 → divisible by 4.316 → last two digits 16 → divisible by 4.118 → last two digits 18 → not divisible by 4. Verification / Alternative check:Direct division: 64/4 = 16, 208/4 = 52, 316/4 = 79, while 118/4 = 29.5 (non-integer). Why Other Options Are Wrong:They satisfy the divisibility-by-4 condition. Common Pitfalls:Checking only evenness; divisibility by 4 is stricter than by 2. Final Answer:118 is not divisible by 4 and is the odd number.

Choose the odd number: Three numbers are divisible by 4; one is not. Identify the number that is not a multiple of 4.
