Question

If a certain number of workmen can do a piece of work in 25 days, in what time will another set of an equal number of men do a piece of work twice as great, supposing that 2 of the first set can do as much in an hour as 3 of the second set can do in an hour?

Answer 1

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 .
