Answer»

Let the cost price of each pen be x

Cost of 12 pens is 12x

Also selling price of 15 pens is the cost price of 12

=SP of 15 pens is 12x

SP of 1 pen is 12x/15

=4x/5

Cost Price>Selling Price

Loss=CP-SP

=x-4x/5

=(5x-4x)/5

=x/5

Loss% = Loss/CP*100%

=x/5*1/x*100%

=100/5%

=20%

The loss % is 20%
