Answer 1

$\Huge{\boxed{\mathcal{\red{ANSWER}}}}$

Let the CP of each pen be Rs.x.

Let the CP of each pen be Rs.x.Then,

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12SP of 12 pens=CP of 15 pnes=Rs.15

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12SP of 12 pens=CP of 15 pnes=Rs.15now,gain=SP-CP=Rs.(15-12)=Rs.3

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12SP of 12 pens=CP of 15 pnes=Rs.15now,gain=SP-CP=Rs.(15-12)=Rs.3gain%=gain/cp*100

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12SP of 12 pens=CP of 15 pnes=Rs.15now,gain=SP-CP=Rs.(15-12)=Rs.3gain%=gain/cp*100 =(3/12*100)%=25%

Let the CP of each pen be Rs.x.Then,CP of 12 pens=Rs.12SP of 12 pens=CP of 15 pnes=Rs.15now,gain=SP-CP=Rs.(15-12)=Rs.3gain%=gain/cp*100 =(3/12*100)%=25%Hence,the gain=25%.
