Answer:
Answer:
There are 120 men
Step-by-step explanation:
let , the number of men is x.
A certain number of men can finish a piece of work in 100 days
Work done = 100x
there were 20 men less it will take 20 days more for the work to be finished.
So, Number of men =x-20
No. of days =120
Work done = 120(x-20)
100x=120(x-20)
\frac{100}{120}=x-20
120
100
=x−20
x=120x=120
Hence there were 120 men.
