Question

6. A boys two pens at 20 each,
He sells one ot gain of 5% and other
at a loss of so%. Find his
gain or Lass
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.
