A shopkeeper gives a discount of 10% on the marked price. If the selling price is ₹6,750, then find the discount.

Correct option is A

Given:

Selling Price =₹6750

Discount =10%

Formula Used:

Discount $$= \frac{Discount percent}{100} \times Original\ Value$$​​

Selling Price = Marked Price - Discount

Solution:

Let the marked price be x

Then discount = 10% of x = 0.1x

Selling Price = x - 0.1x = 0.9x

0.9x = 6750

​$$x= \frac{6750}{0.9} = ₹7500$$​​

Discount = 7500 - 6750 = ₹750

Alternative Method:

Let marked price be 100

Discount = 10% of 100 = 10

Then selling price = 100 - 10 = 90

90 = 6750

​$$1 = \frac{6750}{90}$$​​

​$$10 = \frac{6750}{90} \times 10 = ₹750$$​​
