Problema Solution

the weight of two boys are in the ratio 8:13 if they each reduced by 6 pounds the ratio is 3:5 find their weights now

Answer provided by our tutors

let 'x' and 'y' represent the weight of the two boys


the weight of two boys are in the ratio 8:13


x : y = 8 : 13 cross multiply


13x = 8y


if they each reduced by 6 pounds the ratio is 3:5


(x - 6) : (y - 6) = 3 : 5 cross multiply


5(x - 6) = 3(y - 6)


by solving the system of equations


13x = 8y

5(x - 6) = 3(y - 6)


we find


x = 96 lbs


y = 156 lbs
