Question 987346: a 700 gram dry fruits pack costs rs. 72 . it contains some cashew kernel and the rest as dry grapes. if cashew kernel cost rs. 96 per kg , and dry grapes cost rs. 112 per kg, what were the quantities of the two dry fruits separately? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x=cashew; costs .096/gm
y=grapes; costs .112/gm
y=700-x
So .096x + 0.112(700-x)=72
.096x+78.4-0.112x=72
-0.016x=-6.4
16x=6400
x=400 gm
700-x=300 gm
Cashews are 400 gm and at cost of 38.4 R
Grapes are 300 gm and at a cost of 33.6 R
That is 700 gm at a cost of 72 R.
