An article costs Rs.200, is marked 25% above cost price, and is then sold at a discount of 10% on the marked price. What is the shopkeeper's profit percentage? 
A10%
B12.5%
C15%
D20%
Answer & Solution
Correct answer: B. 12.5%
First mark up the article: marked price $=200\times 1.25=250$. Then apply the 10% discount: selling price $=250\times 0.9=225$. Profit $=225-200=25$, so profit percent $=\frac{25}{200}\times 100=12.5\%$.
