Three successive discounts of 15%, 20% and 25% are given. What will be the net discount in percentage?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 49%.
Calculations:
Equivalent discount of two successive discounts of 15% and 20%
= 15 + 20 - (15 × 20)/100 = 35 - 3 = 32%
Equivalent discount of two successive discounts of 32% and 25%
= 32 + 25 - (32 × 25)/100 = 32 + 25 - 8 = 49%
Hence, the required discount = 49%
