Question

If the cost price of pens is equal to the selling price of pens, find the loss percent. ​

Answer 1

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.

Loss %=
