Question

At what percentage above the cost price must an article by market so as to gain 20 % after allowing a discount of 20%??

Answer 1

Hey sup!

Let the cost price be 100Rs.
Gain=20%
Selling price = 100x(1+20/100)=120Rs.

We have to mark the article at such price that after discount it's selling price is 120Rs.
So let the Marked price be x.
Discount=20%.
selling price=x(1-20/100)=x*80/100= 80x/100.

So, 80x/100=120.
=>x= 120/80 ×100.
=>x= 150Rs.

So if we mark the price at 150Rs that means 50/100 ×100 = 50% above the cost price so to gain 20% after giving discount of 20%.

Hope it helps.
