Calculating the Original Price of the Item

To calculate the original price of the item, we can use the information provided. The price of the item first increased by 10%, then decreased by 20%, and the final price was 660 TG.

Let's denote the original price as P.

1. After the 10% increase, the price became 1.1P. 2. After the 20% decrease from 1.1P, the price became 0.8 * 1.1P.

According to the given information, 0.8 * 1.1P = 660.

Calculating the Original Price

To find the original price P, we can use the equation:

0.8 * 1.1P = 660

Solving for P: P = 660 / (0.8 * 1.1)

Calculating the Original Price

Using the given equation: P = 660 / (0.8 * 1.1) = 750

So, the original price of the item was 750 TG.
