Question 56

An article is sold at two successive discounts of 10% and 20%.If the selling price is ₹1080, then what is the marked price?

Solution

formula of successive discount =$$ d1 + d2 - (d1\times d2) \div 100 $$

= $$ 10%+ 20% -10%\times 20% \div 100 $$

= 28%

Let us consider 100 as marked price and

discount is count on marked price so discount

= $$\frac{28}{100}\times100 $$

Discount = 28

Selling price = 100- 28 =72 which is equal to 1080

72= 1080

1= $$1080\div 72$$

1 =15

So

100 = $$15\times 100$$

= 1500

So marked price is Rs 1500
