Question

12 men and 16 boys can do a piece of work in
5 days. 13 men and 24 boys can do the same work in 4 days.
How long will 7 men and 10 boys take to do the same work?​

Answer 1

Answer:

Now, 12 M + 16B can do work in 5 days. So, 12 M + 8 M can do work in 5 days. So, 20M can do work in 5 days. Hence, if 20M can do work in 5 days, 12M can do work in (20*5)/12 = 8.33 days.
