Answer 1

Answer:

Cost Price is the amount in which a person buys the item.

Selling Price is the amount in which a person sells the item.

Let the price of a costly calculator be x.

Then price of another calculator will be (900 - x)

Then the Selling price of costly calculator will be: {∵ It is selling at loss of 20%)

and the Selling price of another calculator will be: {∵ It is selling at profit of 20%)

Also it is given that selling price of both calculator is same. So we can write it as:

⇒ 2x = 3(900 - x)

⇒ 2x = 2700 - 3x

⇒ x = 540

Then price of other calculator is 900 - 540 = 360.

Hence, the price of both calculators is Rs. 540 & Rs. 360.
