Question

A man buys two pens at rupees 20 each. He seels one at a gain of 5 percent and other at a loss of 5 percent. Find his gain or loss percent

Answer 1

Step-by-step explanation:

CP of first pen=20

G%=5%

Sp=(100+G%)/100×Cp

= 105/100×20

=21

Cp of Second pen=20

L%=5%

Sp=(100-L%)/100×Cp

=95/100×20

=19

Total cp=20+20=40

Total sp=21+19=40.

So, Cp=Sp there is no loss and no gain
