Problem-Solving and Data Analysis practice question

Answer: B. 15

60% = 0.60, so 0.60 × 25 = 15. Quick check: 10% of 25 is 2.5, and 6 × 2.5 = 15. The trap is picking 10 (the number who do NOT play, which is 40%).

Why the other answers are wrong

A. 10

That's the 40% who do *not* play a sport; the question asks for the 60% who do.

C. 18

18 isn't produced by a standard slip on these numbers — 60% of 25 is 0.60 × 25 = 15 (check with 10% of 25 = 2.5, times 6).

D. 20

20 is 80% of 25, not 60%; multiply 25 by 0.60 directly.
