Question

By selling a LED for 18000, a dealer loses 10%. For how much should he sell this LED to gain 30%?​

Answer 1

Given:

Selling price of a LED = 18000

Loss of the dealer = 10%

To find:

The selling price of the LED to gain 30% profit

Calculation:

The loss of the dealer will be added to the selling price of the LED to obtain the cost price of the LED

Cost price of the LED = 18000+18000(10/100)

                                    = 18000+1800

                                    = 19800

Selling price to gain 30% profit = 19,800+19,800(30/100)

                                                    = 19,800+5940

                                                    = 25,740/-

The dealer should sell the LED at 25,740/-
