A shopkeeper marks the price of an article at 200. After allowing a discount of 10\%, he still gains 20\% on the cost price. What is the cost price of the article?
- A. 170
- B. 160
- C. 150 ✓
- D. 120
Correct Answer: C. 150
Explanation
Selling price = 200 \times 0.90 = 180. Since there is a 20\% profit on cost price (CP), 1.2 \times CP = 180 \implies CP = \frac{180}{1.2} = 150.
