ArithmeticPercentage, Profit & Loss
A man bought an article for ₹ 21. What was the marked price of the article if he had bought the article at 30% discount?
- a.₹ 30
- b.₹ 32
- c.₹ 33·50
- d.₹ 35
Answer: (A) ₹ 30
Paying ₹ 21 after a 30% discount means ₹ 21 is 70% of the marked price. Marked price = 21 ÷ 0·7 = ₹ 30. Adding 30% to ₹ 21 would give about ₹ 27·30, which is the usual mistake.
