A businessman allows a discount of 10% on the marked price. How much above the cost price must he mark his goods to make a profit of 17%? [BSSC (CGL) 2015] |
A) 30%
B) 20%
C) 27%
D) 18%
Correct Answer: A
Solution :
Let the cost price be Rs. 100. |
Then, selling price \[=100\times \frac{(100+17)}{100}=Rs.\,117\] |
Marked price \[\times \frac{90}{100}=117\] |
\[\Rightarrow \] Marked price \[=\frac{117\times 100}{90}=Rs.\,130\] |
Hence, he marks 30% above the cost price. |
