A shopkeeper offers a festive offer: buy any three shirts, get two free. Find the equivalent percentage discount for the offer.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 40%.
Buy 3 shirts, get 2 free → Pay for 3 shirts, get 5 shirts total.
Cost of 5 shirts = Price of 3 shirts
So, effective cost per shirt = 3/5 = 0.6 (i.e., 60% of original price)
Discount = 100% - 60% = 40%
