The percentage profit earned by selling a mobile for ₹12,000 is equal to the percentage loss incurred by selling the same mobile for ₹9,000. At what price should the mobile be sold to make 20% profit.

₹12,600

First selling price = 12000

Second selling price = 9000

The cost price = \(\frac{First\;  selling \; price + Second \;  selling \; price}{2}\) = \(\frac{12000+ 9000}{2}\) = 10500

Profit% = 20%

Then the new selling price = 120% of 10500 = ₹12,600
