Answer:

LET the C.P. of 1 pen =Re. 1

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 PENS=Rs. 12×1

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, given

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %=

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100=

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100= 16

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100= 164

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100= 164

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100= 164 ×100

Let the C.P. of 1 pen =Re. 1∴ C.P of 12 pens=Rs. 12×1=Rs. 12Hence, givenC.P. of 12 pens = S.P of 16 pens∴ S.P of 16 pens=Rs. 12∴ C.P of 16 pens=Rs. 16∴ Loss=C.P−S.P=16−12=4 Rs.Loss %= C.PLoss ×100= 164 ×100=25%.
