**Question 1: **Jim buys a shirt for 400 Rs in a sale. If its original price is Rs 600, Calculate its discount rate.

** Solution: **
Given: Original Price of the shirt = Rs 600

Sale Price of the shirt = Rs 400

The Percentage off is given by

Percentage off = (1 -

$\frac{Sale Price}{Original Price}$) $\times$ 100 %

= (1 - $\frac{400}{600}$) $\times$ 100 %

= (1 - 0.6667) $\times$ 100 %

= 0.333 $\times$ 100 %

= 33.33%

$\therefore$ 33.33% off is there on the shirt.

**Question 2: **A Whole sale was put in a market on groceries. Mary buys Milk, jam and sugar for Rs 100. If their marked price as a whole is Rs 125, Calculate the Percentage off?

** Solution: **

Given: Original Price for the item = Rs 125

Sale Price for the item = Rs 100

The Percentage off is given by

Percentage off = (1 - $\frac{Sale Price}{Original Price}$) $\times$ 100 %

= (1 - $\frac{100}{125}$) $\times$ 100 %

= (1 - 0.8) $\times$ 100 %

= 0.2 $\times$ 100 %

= 20 %

$\therefore$ 20 % off is there on the groceries.
