Question

A shopkeepr gives 11% discount on a television set hence a cost price of it is Rs.2,2250 then find the market price of the television set​

Answer 1

The marked price of the television set is 25000.

Step-by-step explanation:

Given that:

A shopkeeper gives 11% discount on a television set hence a cost price of it is Rs. 22,250.

To Find:

The marked price of the television set.

Let us assume:

The marked price of television set be Rs x.

Formula used:

➨ SP = {(100 - Discount%) × MP}/SP

Where,

➨ SP = Selling price

➨ MP = Marked price

Finding the selling price:

⟶ SP = {(100 - Discount%) × MP}/100

⟶ SP = {(100 - 11) × x}/100

⟶ SP = {89 × x}/100

⟶ SP = 0.89x

∴ Selling price = Rs 0.89x

Now we have:

Selling price of TV set = Rs 22,250

Because the given amount is the cost price of TV set for the customer but selling price for the shopkeeper.

Finding the marked price:

According to the question.

⇒ 0.89x = 22250

⇒ x = 22250/0.89

⇒ x = 25000

∴ Marked price = Rs 25000

Answer 2

We have to use this formula for finding MP : MP - Discount = SP. Let us keep MP as x . SP = CP= 22250 Discount = 11% . So, x - 11/100x = 22250 , 89/100x = 22250
x = 22250/89x100= 25,000.
