Question

20 men can do a piece of work in 20 days
. How many should more persons
require to finish the work in 8 days?
​

Answer 1

Step-by-step explanation:

20 men working together finishes work in 20 days, If 25 men working together it would be x days.

So, 20×20=25×x

x=16 days

Answer 2

Solution:-

Inverse proportion exists between the number of men and time.

In 20 days 20 men's are required.

So, in one day men required = 20 × 20 = 400

Hence, in 8 days men required = 400/8 = 50

Hence, in 8 days men required = 50
