Question

the cost price of 16 pens is equal to the selling price of 12 pens find the gain or loss percent​

Answer 1

The gain percentage (%) = 25 %

ANSWER

Let the C.P. of 1 pen =Re. 1

∴ C.P of 12 pens=Rs. 12×1

=Rs. 12

Hence, given

C.P. of 12 pens = S.P of 16 pens

∴ S.P of 16 pens=Rs. 12

∴ C.P of 16 pens=Rs. 16

∴ Loss=C.P−S.P

=16−12

=4 Rs.
