33.33% or 33 1 %

                      3

Step-by-step explanation:

pens are bought for 12 for a rupees

so cost of 12 pens price = 1

so cost of 1 pen = 1/12

it is sold at 9 for a price

so selling price of 9 pens =1

so cost of one pen = 1/9

1/9-1/12

=4-3/36

1/36

gain %= gain/cp ×100

=1/36/1/12 ×100

=12/36×100

=33.33

therefore the gain =33.33
