What will be the difference between the sale price (in ₹) of a book with a marked price ₹1,500 under the following discount schemes?
(i) Two successive discounts of 20% each
(ii) Two successive discounts of 30% and 10%
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 15.
Marked Price = ₹1500
Scheme (i): 20% and 20%
1st discount: 20% of 1500 = 300 → New price = 1500 − 300 = 1200
2nd discount: 20% of 1200 = 240 → Final price = 1200 − 240 = ₹960
Scheme (ii): 30% and 10%
1st discount: 30% of 1500 = 450 → New price = 1500 − 450 = 1050
2nd discount: 10% of 1050 = 105 → Final price = 1050 − 105 = ₹945
Difference = 960 − 945 = ₹15
