Question 736812
If a piece of work could be completed in 24 days by 98 men. How many men would take to complete it in 21 days ?


24 days = 98 men

21 days = x men

Cross multiply:

24 * x = 98 * 21

24x = 2058

Divide each side by 24

24x/24 = 2058/24

x = 85.75

There is no 0.75 (three quarters) of a man.

Therefore:

We round up x to 86 men


Answer:

86 men
