Answer 2

Answer:

The cost of 20 pens is ₹ 800 .

Step-by-step explanation:

Given information,

the cost of 5 pens is ₹ 200

We have to find out the cost of 6 pens

As,

The cost of 5 pens = 200

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

The cost of 1 Pen $= \frac{200}{5}$

By dividing 200 by 5 we get

The cost of 1 pen = 40

The cost of 20 pens = The cost of 1 pen × 20

The cost of 20 pens = $40 \times 20$

The cost of 20 pens = $800$

Hence,

The cost of 20 pens is ₹ 800 .
