Question

Samant brought microwave oven and paid 10% less than the original price. He sold it with 30% profit on the price he had paid. What percentage of profit did Samant earn on the original price?

• A. 17%
• B. 20%
• C. 27%
• D. 32%

Answer 1

Answer: (A)

17%

Lets assume original price of the microwave oven = Rs. 100
So, buying price for samant = Rs. 90
Profit $\%=30\%=\frac{p\times 100}{Costprice}$
$30\%=\frac{p\times 100}{90}$
$30\times 90100=p$
$profit=27$
Selling price =90+27=117 Rs
Profit =117-100=17 Rs
profit $\%=\frac{17\times 100}{100}=17$
