Answer:

he need to sell 32 pens for rs 96( for getting 20% profit

Step-by-step explanation:

SP of 90 ball pens is =180 Rs. at the loss of 20%.

CP of 90 ball pens is=180*100/80

=18*100/8

=18*25/2

=9*25

CP =225

CP of 1 ball pen is=225/90

=2.5 Rs.

He want to gain 20%.

The new SP is=2.5*120/100

=3 Rs.

So he will sell 20%=96/3

=32 ball pens.
