Question

10 men can do the work in 4 days in how many day 8 men do it?

Answer 1

Hello dear

It is inverse variation.

x*y = k(constant)

=> 10*4 = 8*y

=> 40 = 8y

=> 40/8 = y

=> 5 = y

Hence, 8 men will complete the same work in 5 days.

Hope it helps.

Answer 2

Here we can follow unitary method which js quite simple


10 men do a piece of work in 4 days
1 man can do it in =4*10days=40days
8 men can do it in = 40/8days= 5days

The required answer is 5 days.
hope it helps u.
