Question

A shopkeeper sells 80 pens for ₹7,200 at the profit of ₹10 per pen. What is the profit percentage?

• A. 11%
• B. 25%
• C. 10%
• D. 12.5%

Answer 1

The correct option is D 12.5%

Given, Shopkeeper sells 80 pen at profit of ₹10 per pen.
$⟹$Total profit shopkeeper made after selling 80 pen $=80\times ₹10=₹800$

And we know that,
$\text{Profit = Selling price - Cost price}⟹\text{Cost price}=\text{Selling price}-\text{Profit}$

And selling price of 80 pens is given as ₹7200.
$⟹\text{Cost price}=₹7200-₹800=₹6400$

Now,
$\text{Prifit percentage}=\frac{\text{Profit}}{\text{Cost price}}\times 100⟹\text{Prifit percentage}=\frac{800}{6400}\times 100=\frac{100}{8}=12.5\%$

Hence, option 'd' is correct.
