Gain or loss percent = X + Y +(X×Y)/100

For increase use positive sign and for decrease use negative sign.

So here, X = +20%

And Y = -10% negative as it is discount

Put the values of X and Y in the above formula, if solution is positive it is gain and if it is negative it is loss.

=20 + (-10) + (20 × -10)/100

=20 - 10 - 200/100

= 20 - 10 - 2

= 8

It is positive so there will be profit of 8% in this transaction.
