Question

Aarati bought 10 dresses at Rs 6300. She paid Rs 200 extra as expenses. If she sold all the dresses at the cost of Rs 780 per dress, how much percentage profit or loss does she make?

• A. 20% profit
• B. 20% loss
• C. 40% profit
• D. 30% profit

Answer 1

The correct option is A 20% profit

Cost price of $10$ dresses is $Rs.6300$ and expanses is $Rs.200$.

So, cost price after expanses$=Rs.(6300+200)=Rs.6500$

Also, selling price of $1$ dress is $Rs.780$.

Hence, selling prince $10$ dresses$=10\times 780=Rs.7800$

Now, $SP>CP$, so their will be net profit.

So, profit percent is,

$Profit\left(\%\right)=\frac{7800-6500}{6500}\times 100=\frac{1300}{65}=20\%$
