Question

a man buys two pen at rupees 20 each he sell one at gain of 5% and other at a loss of 5% find the gain or loss percent

Answer 1

CP of one pen =20

Gain=5%

Let profit be x.

x/20*100=5

5x=5

x=5/5

=1

Let loss be y

y/20*100=5

=5y=5

=y=5/5=1

Thus loss=profit=1

Thus there is neither profit nor loss
