Hammers and wrenches are manufactured at a uniform weight per hammer and a uniform weight per wrench. If the total weight of two hammers and three wrenches is one-third that of 8 hammers and 4 wrenches, then the total weight of one wrench is how many times that of one hammer?
Choose one:
A) 1/2
B) 2/5
C) 1
D) 3/2
E) 2
x bé the weight of a hammer and y be the weight of a wrench.   (2x+3y)=1/3*(8x+4y)   3(2x+3y)=(8x+4y)   6x+9y=8x+4y   5y=2x   y=2x/5   Ans - 2/5
