What is the effective discount percent (rounded off to 2 decimal places) if a shopkeeper offers a scheme, “buy five and get one free”?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 16.67%.
Total toys = 6
Customer pays for = 5
So, effective price of 1 toy = 5 ÷ 6 of cost price
Discount = 1 – (5/6) = 1 ÷ 6
Discount % = (1/6) × 100 = 16.67%
