Step-by-step explanation:
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.
