1. A man binds 112 books iin a day and his assistant work 1/4 as fast. How many days will it take them to bind 560 books, if each alone works on alternate days?
- A. 8
- B. 8
- C. 8
- D. 8
Answer: Option A
Explanation:
His assistant binds 1/4 x 112 = 28 books a day.
So, they bind 112 + 28 = 140 books in every 2 days working in alternate days
They will need 560/140 x 2 days = 8 days.
