A shopkeeper marks his goods 20% above cost price, but allows 30% discount for cash. His net loss is

A) 8%

B) 10%

C) 16%

D) 20%

Correct Answer: C

Solution :

Let the cost price be Rs. x.

Mark price \[=\left( 1+\frac{20}{100} \right)x=12x\]

Cash price \[=\left( 1-\frac{30}{1000} \right)1.2x=0.7\times 1.2x=0.84x\]

Net loss \[=x-0.84x=0.16x\]

\[\therefore \] Net loss\[=\frac{0.16x}{x}\times 100=16%\]
