Answer 2

Answer :

The cost of 18 pens is 216

Step by step Explanation :

Given information,

the cost of 5 pens is 60

We have to find out the cost of 18 pens

As,

The cost of 5 pens = 60

The cost of 1 pen = $\frac{the \: cost \: of \: 5\: pens }{5}$

The cost of 1 Pen $= \frac{60}{5}$

By dividing 60 by 5 we get

The cost of 1 pen = 12

The cost of 18 pens = The cost of 1 pen × 18

The cost of 18 pens = $12 \times 18$

The cost of 18 pens = $216$

Hence,

The cost of 18 pens is 216 .
