Question
The marked price of an electronic watch in a store is ₹15,620 and it is available at a discount of 27%. What is the price (in ₹, to the nearest tens) that a customer pays?
- A. 11,400 (Correct answer)
- B. 9,880
- C. 2,500
- D. 10,800
Correct Answer
Option A — 11,400
Detailed Solution & Explanation
The correct answer is ₹11,400.
Key Points
- Price paid $=15620\times(1-0.27)=15620\times0.73=11402.6$.
- Rounded to the nearest tens $=$ ₹11,400.
Additional Information
- A discount of d% means paying (100 − d)% of the marked price, so a single multiplication by 0.73 does the whole job.
- Successive discounts do not add: two discounts of a% and b% give an effective a + b − ab/100 per cent.
- Read the rounding instruction — to the nearest tens turns 11,402.6 into 11,400, not 11,403.
