Question: A shopkeeper sells a shirt for $30 after giving a discount of 25%. What was the original price of the shirt?
Options:
Correct Answer: $40
Solution:
Let the original price be x. After a 25% discount, the selling price is x - 0.25x = 0.75x. Setting this equal to $30 gives 0.75x = 30, so x = 30/0.75 = $40.
