Question

A shopkeeper sells his goods at 80% of its cost price. Find his per cent gain or loss?

• A. 20%
• B. 30%
• C. 25%
• D. 15%

Answer 1

The correct option is A

20%

Let C.P. of goods = ₹100
$\therefore$ S.P. of goods = $\frac{80}{100}\times 100=₹80$
Loss = C.P. - S.P.
=₹100 - ₹80 = ₹20
$\text{Loss}\%=\frac{\text{Loss}}{C.P.}\times 100$
$=\frac{20}{100}\times 100=20\%$
