The marked price of a shirt is ₹ 750. If a discount of 20% is allowed, what is the selling price ?

Answer: B

The selling price is ₹ 600.

A discount is taken on the marked price:

\[ \begin{aligned} \text{Discount} &= 20\% \text{ of } 750 = 150 \\ \text{SP} &= 750 - 150 = 600 \end{aligned} \]

Equivalently, the customer pays 80% of the marked price, and 0.8 times 750 is 600.

₹ 625 would be a discount of about 16.7%, ₹ 650 a discount of about 13.3%, and ₹ 580 a discount of about 22.7%, none of which is 20%.
