A shopkeeper gives 4 shirts free on buying 6 shirts. Find the percentage of discount given to the customers?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 40%.
Total shirts received = 6 (paid) + 4 (free) = 10 shirts
Shirts paid for = 6
So, effective price paid per shirt = 6/10 = 0.6 of original price
That means the customer gets a 40% discount
