5 men and 2 boys working together can do four times as much work as a man and a boy. Working capacities of a man and a boy are in ratio?

Question

Work word Problem

Answer 1

Now that the problem has been corrected(eliminating women), I translate this statement into 

5m + 2b = 4(m + b), with obvious notation for men & boy work output rates.

 

m = 2b.  Now you can answer the question about ratio!
