Answer 2

• As per the data given in the question, we have to determine the value of the given expression.

       Given data:- Cost price of $200$  Pen is $81.2.$

       To find:- the cost of $1$ pen=?

       Solution:-

• Cost price of $200$ pen is $81.2.$
• So, the cost price of one pen, we will divide the $81.2$ by $200.$

       $\Rightarrow \frac{81.2}{200}=\frac{81.2\times10}{200\times10}=0.40.$

    Hence, the value cost of $1$ pen is $0.40.$
