Answer:
110
Step-by-step explanation:
Let the original number of men=x.
So, x men finish the work in100days.
After 10 men leave,
x−10 men finish the work in (100+10)=110days.
Now the number of men is inversely proprtional to the number of days
in which they finish the work.
∴
x−10
x
=
100
110
⟹100x=110x−1100
⟹x=110.
So the original number of men was 110.
