Let the CP of each pen be Rs.x.

Then,

CP of 12 pens=Rs.12

SP of 12 pens=CP of 15 pnes=Rs.15

now,gain=SP-CP=Rs.(15-12)=Rs.3

gain%=gain/cp*100

         =(3/12*100)%=25%

Hence,the gain=25%.

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

Therefore,

The C.P of 15 pens = Rs. 15

Given,

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

So, S.P of 12 pens = Rs.15

Selling Price of 1 pen = Rs. 1.25

Gain= Rs. 0.25

Gain percent= Gain x 100/C.P %

  = 0.25 x 100/1 %

  =25/1 %

  = 25 %

Therefore, the gain percent is 25%

Hope You understood it... :-)

27 - 15 = 12

(12/27) × 100 = 40% loss
