Answer 1

Given: Ravi bought a car at 30% discount , he sold it with 50% increase on the price.

To find: The new sale price is by what percent more than the original price.

Solution:

• Now we have not given the original price.

• So let the original price be Rs 100.

• The cost price will be:(100 - 30)% of 100

            = 70% x 100

            = 70/100 x 100

            = Rs 70.

• Selling price will be incresed by 50%, so:

• Selling price is: 150% of 70

            = 150% x 70

            = 150/100 x 70

            = 3/2 x 70

            = 3 x 35

            = Rs 105

• So the requires percentage will be:

            = ( 105 - 100 / 100 ) x 100

            = 5%

Answer:

         The new sale price is by 5% percent more than the original price.
