What was the original price of an item if a discount of 20 percent reduced the price to Rs. 100?

Explanation

Since a 20% discount reduced the price to Rs. 100:

x - (20% of x) = 100

To find 20% of x, multiply x by 0.20:

x - 0.20x = 100

Combine like terms:

0.80x = 100

Divide by 0.80:

x = 125
