22 men can make a wall in 2 days. How many men are required to complete the same work in half a day?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 88 .
22 men can complete the work in 2 days.
Total man-days = 22 men × 2 days = 44 man-days.
Let ( x ) be the number of men needed to complete the work in 0.5 days.
⇒ x × 0.5 days = 44 man-days
⇒x =44 / 0.5 = 88
