On selling an article for Rs. 7200, a person losses 25% of its cost price. At what price he should sell it to gain 25% on its cost price?

12000

Loss of 25% ⇒ 75% of C.P. = 7200

                        1% of C.P. = \(\frac{7200}{75}\)

                     100% of C.P. = 9600

To gain 25%, article selling price must be 125% of CP

            SP = \(\frac{9600 × 125}{100}\) = 12000
