Question

A dry fruit packet of 700gm is consisting of some cashew nuts and raisins. If rate of cashew nut is 1/2 rs/kg and rate of raisins is 96rs/kg. Then determine the separate quantity of cashew nut and raisins mixed within the packets.​

Answer 1

Answer:

72

Step-by-step explanation:

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.
