Now,

Loss percentage $=$

$\dashrightarrow \tt \frac{30}{120} \times 100$

$\dashrightarrow \tt \cancel \frac{30}{120} \times 100 = \frac{1}{4} \times 100$

$\dashrightarrow \tt \frac{1 \times 100}{4} = \frac{100}{4}$

$\dashrightarrow \tt \cancel \frac{100}{4} = 25 \bf\%$

$\Huge\therefore$Loss percentage of the pen is 25 $\bf \%$
