Answer 2

Given : 20 men can complete a work in 8 days.

To find : How many days 10 men will take to complete the half of that work?

Solution :

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will be using normal arithmetic method.

Let, total work = 1

20 men can complete 1 amount of work in = 8 days

1 man can complete 1 amount of work in = (8×20) days

1 man can complete ½ amount of work in = (8×20)/2 days

10 men can complete ½ amount of work in = (8×20)/(2×10) = 8 days

Hence, 10 men will complete half of that work in 8 days
