Answer 2

Answer:

The cost of 3 pens is ₹ 85.5 .

Step-by-step explanation:

Given information,

the cost of 5 pens is ₹ 142.5

We have to find out the cost of 3 pens

As,

The cost of 5 pens = ₹ 142.5

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

The cost of 1 Pen $= \frac{142.5}{5}$

By dividing 142.5 by 5 we get

The cost of 1 pen = 28.5

The cost of 3 pens = The cost of 1 pen × 3

The cost of 3 pens = $128.5 \times 3$

The cost of 3 pens = $85.5$

Hence,

The cost of 3 pens is ₹ 85.5 .
