Arindam purchased a coat for Rs.2100 after getting a discount of 20% and but than paying GST at a rate of 5% on the discounted price. Find the marked price of the coat.

Correct option is D

Given:

Selling price (after discount) = Rs. 2100

Discount rate = 20%

GST rate = 5% (on discounted price) 

Formula Used: ​

Price after discount = Marked Price $$\times \left( 1- \frac{dicount \%}{100}\right)$$ 

Solution: ​

5% GST is paid , So the Price paid by Arindam 

= Price after discount + 5% GST 

2100 = Price after discount + 5% GST 

Price after discount = $$\frac{2100}{105}\times 100 = 2000$$ 

Now , 

Marked Price = $$2000 \times \frac{100}{80} = ₹2500$$
