10 typists can type 600 pages in 8 hours. What is the average number of pages typed by each typist in an hour?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 7.5
The work is shared among 10 typists and spread over 8 hours, so the total pages are divided by both.
Pages typed by one typist in 8 hours \(\displaystyle =\frac{600}{10}=60\)
Pages typed by one typist in one hour \(\displaystyle =\frac{60}{8}=7.5\)
Each typist types on average 7.5 pages an hour.
