Step-by-step explanation:
x persons of first group can do work in 25 days.
2 men of first group = 3 men of second group , then x persons of second group = 2x/3 persons of first group.
x persons of first group can do work in 25 days.
2x/3 persons of first group can do work in 25 *3/2 = 75/2 = 37.5 days .
