Solution for yesterday’s problem

Let the selling price of the first radio is $100

His gain percent is 10; therefore his cost price is (100/110)*100 = $10000/110

Let the selling price of the second radio is $100

His loss percent is 10; therefore his cost price is (100/90)*100 = $10000/90

His total cost price is $20000/99 and selling price is $200.

His total cost price is more than his total selling price.

Net loss is 1%

Fastrac method

10-10+(10*-10)/100 = -1%

Negative sign indicates loss.
