EPFO 2015 English Medium Solved Paper

Cost of first type of rice = $25\times 32$ = $\mathit{R}\mathit{s}.800$
Cost of second type of rice = $20\times 35=\mathit{R}\mathit{s}.700$
Total cost of $\left(25+20\right)=45$ kg mixed rice
$=800+700$ = $\mathit{R}\mathit{s}.1500$
Cost of 1 kg mixed rice= $\mathit{R}\mathit{s}$ . $\frac{1500}{45}$
SP of 1 kg mixed rice $\frac{=\mathit{C}\mathit{P}\times (100+\mathrm{Profit}\%)}{100}$
$=\frac{1500}{45}\times \frac{\left(100+15\right)}{100}=\frac{115}{3}$
$=\mathit{R}\mathit{s}.38.33/$ $\mathit{k}\mathit{g}$
