Answer:
Let us assume that he sells x pens for a profit of 12% and hence (60−x) pens at a loss of 8%
Let C.P of a pen be Rs.1.
Profit Loss
CP=x CP=60−x
P%=12%L%=8%
SP=CP(
100
100+P%
)SP=(60−x)(
100
100−8
)
SP=x(
100
100+12
)=
100
92(60−x)
=
100
112x
=
25
28x
25
23(60−x)
Overall
CP=x+60−x=60.
SP=
25
28x+23(60−x)
=
25
1380+5x
P%=
5.60

×100=11

x−24
=11
x−24=33⇒x=24+33=57
Hence 57 pens were sold at a profit 12%
