Discount Rate Example Problems

Let’s learn how to find the discount with the help of examples.

Question 1: Ruby purchased the shirt. That shirt rate was $2000 at a 10% discount. Find a discount rate? And then Ruby how many dollars give to the cashier?

Solution:Here,Principal amount p = 2000 dollars

Interest rate r = 10%

Discount rate DR = pr

DR = 2000* 10% = 200

The discount amount for the dress is 200.

Discount rate DR = 200.

Dress rate = principal amount – discount rate

= 1000 – 200 =800

Ricky 800 dollars is given to the cashier.

Question 2: Kavita bought land for 50000 dollars at 20% in the year 2000. Then 2004th year that land was sold for 3000 dollars. How many dollars did she lose?

  • Solution: Principal amount p = 50000 dollars
  • Interest rate r = 20%(I)
  • Discount rate DR = pr = DR = 50000 x 20/100 = 20100 in the year 2000 = 10000
  • Discount rate DR = 1000 dollars in the year 2000.
  • So, the discount amount is 10000 dollars.
  • Discount rate DR = 50000*30/100 in 2004th year
  • Discount rate =15000 dollars.
  • The discount amount is 15000 dollars.
  • Loss Discount rate in 2004th year – the Discount rate in the year 2000

=15000 dollars – 10000 dollars

=5000 dollars

Kavita lost 5000 dollars in that land.
