Answer 2

To find: cost of 3 pens

Given : cost of 13 pens = Rs 104

solution:

• we are given that cost of $13$ pens is $Rs104$.
• Firstly let us find cost of $1$ pen

    cost of $13$ pen = $Rs104$

     hence cost of 1 pen = $\frac{1\times 104}{13}$

                                       $= 13$
