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.


please give me solution it's really urgent...​

Answer 1

Answer:

Since we have given that

Quantity of dry fruits = 700gm

Cost of 700 gm = Rs.144

Let the quantity of cashew nuts be 'x'.

Let the quantity of raisin be '700-x'.

Cost of per kg cashew nut = Rs. 192

So, Cost of per gm = Rs.0.192

Cost of per kg raisin = Rs. 224

Cost of per gm = Rs. 0.224

So, According to question, our equation becomes,

\begin{lgathered}0.192x+0.224(700-x)=144\\\\0.192x+156.8-0.224x=144\\\\-0.032x=144-156.8\\\\-0.032x=-12.8\\\\x=\dfrac{12.8}{0.032}\\\\x=400\end{lgathered}

0.192x+0.224(700−x)=144

0.192x+156.8−0.224x=144

−0.032x=144−156.8

−0.032x=−12.8

x=

0.032

12.8

x=400
