Question

the cost price of 12 pens is equal to the selling price of 18 pens. Find gain or losspercent
​

Answer 1

Step-by-step explanation:

CP of 12 pens = SP of 18 pens

$\color{olive}\[ \begin{array}{l} \tt \dfrac{C P}{S P}=\dfrac{18}{12} \\ \\ \tt C P=18, S P=12 \\ \\ \tt \text { Loss }=18-12=6 \\ \\ \tt\text { Loss } \%=\dfrac{\text { loss }}{C P} \times 100 \\ \\ \tt =\dfrac{6}{18} \times 100 \\ \\ \tt =\dfrac{100}{33} \% \\ \\ \tt=33.33 \% \end{array} \]$

Hence, loss is 33.33 %.
