If 12 students can read 4800 pages of a book in 15 days, then how many students can read 7200 pages of the same book in 10 days?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 27.
12 × 15 × 4800 = x × 10 × 7200
⇒ x = (12 × 15 × 4800) / (10 × 7200) = 864000 / 72000 = 27
