Question

The C.P. of 12 pens is the same as the S.P. of 15 pens. Calculate the profit or loss percent made, if all the pens bought are considered to be sold.​

Answer 1

Step-by-step explanation:

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

∴ C.P of 12 pens= Rs. 12×1

Hence, given,

C.P. of 12 pens = S.P of 15 pens

∴ S.P of 15 pens=Rs. 12

∴ C.P of 15 pens=Rs. 15

∴ Loss=C.P−S.P

= 15 − 12

= 3 Rs.

Loss % = Loss / CP × 100

= 3 / 15 × 100

= 20%
