Answer 2

Given Selling Price = 1755, Gain = 12 1/2 = 12/5%.

Let the cost price be x.

We know that profit% = SP - CP/CP * 100

                         12.5 = 1755 - x/(x) * 100

                        12.5/100 = 1755-x/(x)

                        Multiply both sides by 10.

                        12.5 * 10/100 = 10(1755 - x)/x

                       5/4 = 10(1755 - x)/x

                       5x = 40(1755 - x)/x

                       5x = 70200 - 40x

                        45x = 70200

                           x = 1560.


The cost price = 1560.


Hope this helps!
