43 pls sir I have problem
Dear student,
Let the original no. of men = x.
Number of days taken by the first group = 50days.
Number of days taken by the second group = 50-10=40 days
Number of less days, that is, the work completed earlier =10 days.
It is an inverse variation.
Now,
Thus, the original no. of men = x= 28
Regards
