Question

6. A man buys two pens at ₹20 each. He sells one at a gain of 5% and other at a loss of 5%. Find his gain or loss per cent.​

Answer 1

Step-by-step explanation:

C.P of two pens =Rs.2×20 =Rs.40

CP of one pen=Rs.20, Gain=5%

Gain=Gain%/100×CP

=5/100×20

=Rs.1

SP=CP+Profit or Gain

=Rs.(20+1)=Rs.21

CP =Rs. 20, Loss=5%

Loss=Loss%/100×CP

=5/100×20

=Rs.1

SP=CP-Loss

=Rs.(20-1)=Rs.19

Total SP of two pens=Rs.(21+19)=Rs.40

Since Total SP=Total CP

There is neither gain nor loss.
