please tell me this problem has insufficient data..
5 men and 2 boys working together can do four times as much work as a man and a boy. working capacities of a woman and a boy are in the ratio ... a. 1:2 b. 1:3 c. 2:1 d. 3:1
the solution given is.. Let 1 man's 1 day's work = x and 1 boy's 1 day's work = y then, 12x + 16y= 1/5 13x + 24y=1/4
Solving these two equations, we get x=1/100 and y=1/200 Required ratio= x:y --> 1/100:1/200 -->2:1
