What was the original price?
- 18
- 17

Hint:
When a certain quantity is divided into 100 equal parts and a certain part of it is to be expressed in terms of the whole quantity, that portion is called as a percent, represented with a % sign.
The correct answer is: 18.75

New Price = 80% of the Original Price
To find-
Original Price
Solution-
Let the original price be $x.
New Price = 80% of the Original Price .......................................... (Given)
∴ New Price = 80% of x
∴ New Price = 80/100 * x
∴ New Price = 80x/100
∴ 15 = 80x/100
∴ 15 * 100 / 80 = x
∴ 18.75 = x
Final Answer- Option 'c' i.e. '18.75' is the correct answer to the given question.
