Question

A certain number of men can do a work in 60 days. If there were 8 men more
it could be finished in 10 days less. How many men are there?
​

Answer 1

Step-by-step explanation:

Let the number of men be 'x'

x men will do a work in 60 days

1 man will do the work in 60x days

x+8 men will do a work in (60-10) = 50 days

1 man will complete the work in 50x + 400 days

ACCORDING TO QUESTION :

60x = 50x + 400

or, 60x - 50x = 400

or, 10x = 400

or, x = 400/10

or, x = 40

Therefore there were 40 men in the beginning
