We are taking 2 questions and solving them

ramu .bought a laptop of rupees 1,50,000 at a loss of rupees 15 percent . Find selling price of the laptop.

So here we have to find SP -:

Selling price = 100+profit ×cp/100 and if it is loss so 100- loss

So 100-15×150000/100

So solve it and our selling price is solved

So the answer will be 127,500 . And yes it is correct so how easy to calculate sp now let’s see about cp …
