ArithmeticPercentage, Profit & Loss
A cloth store is offering 'Buy 3, get 1 free'. What is the net percentage discount being offered by the store?
- a.20%
- b.25%
- c.30%
- d.$33\frac{1}{3}$%
Answer: (B) 25%
The customer takes 4 items and pays for 3, so 1 of the 4 items' worth is free. The discount is 1 ÷ 4 = 25% of the total price. $33\frac{1}{3}$% wrongly divides the free item by the 3 paid items.
