d)15/8​

Answer 1

Step-by-step explanation:

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.
