.

Answer 1

Answer:

3 RS IS YOUR ANSWER

Step-by-step explanation:

Let the cost price of the pen be Re 1.

Cost price of 12 pens = Rs 12

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

Gain = SP - CP = Rs (15 - 12) = Rs 3

Gain% = (GainCP× 100 )%

=(312× 100 )%= 25%

Gain% = 25%

Answer 2

Step-by-step explanation:

SP OF 12 PENS =CP OF 15 PENS

SP OF 1 PENS = R. 1

SP OF 12 PENS= R. 12

SP OF 15 PENS = R. 15

CP OF 15 PENS =R. 12

NOW, SP >CP

SO, GAIN = SP -CP

=R. 15 - R. 12 =R. 3

GAIN % = GAIN *100. =3/12 *100 =25%

CP

Answer=25%
