Question

Q4. A certain number of men could do a piece of work in 60 days. If there were 8 more, it
could be finished in 10 days less. Find the number of men in the beginning.​

Answer 1

Answer:

Let there be x men originally.

x men finish the work in 60 days and (x+8) finish it in 50 days.

x men finish the job in 60 days.

1 man can finish it in 60x days.

(x+8) men can finish the job in 50 days.

1 man can finish it in 50(x+8) days.

Therefore,

60x=50(x+8)

10x=400

x=40

Hence, there were 40 men originally.
