​

Answer 1

Answer:

Step-by-step explanation:

loss % = 15-12/15 *100=20%

Answer 2

Answer:

Let the CP of each pen be Rs.x.

Then,

CP of 12 pens=Rs.12

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

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

gain%=gain/CP*100

=(3/12*100)%=25%

Hence,the gain=25%.

Step-by-step explanation:

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%
