What is 15% of 240?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

36

  1. A 40
  2. B 24
  3. C 30
  4. D 36

Why this is the answer

15% of 240 = 0.15 × 240 = 36. Convert percent to decimal (÷100) then multiply. A fast mental route: 10% of 240 is 24, and 5% is half of that, 12, so 15% = 24 + 12 = 36. The distractor 24 is 10%, 30 is 12.5% and 40 is roughly 16.7% — the test often offers a nearby percentage as a wrong answer, so check your work against the easy 10% benchmark.
