Difficulty: Easy
Correct Answer: 48
Explanation:
Introduction / Context:We are equating two percent-of quantities. Compute one side, then solve the simple percentage equation on the other side to find the unknown number.
Given Data / Assumptions:
Concept / Approach:Use the fact that 12.5% = 1/8 and 50% = 1/2 to speed up arithmetic. Compute 1/8 of 192; then set 1/2 * ? equal to that value and solve.
Step-by-Step Solution:
12.5% of 192 = (1/8) * 192 = 24.Set 50% of ? = 24 ⇒ (1/2) * ? = 24.Thus, ? = 48.Verification / Alternative check:Check: Half of 48 is 24 — matches 12.5% of 192.
Why Other Options Are Wrong:
Common Pitfalls:Misreading 12.5% as 12.5/100 without simplifying to 1/8, which is a convenient equivalence.
