If a price is reduced by 10% and then again reduced by 20%, what is the overall percentage decrease?
Show answer & explanation
Correct answer: A
Explanation
Initial price of the item = ₹100
New price = 100 × 90/100 × 80/100 = ₹72
Total reduction = ₹100 − ₹72 = ₹28
Total percentage reduction = (28/100) × 100 = 28%
