Answer 2

Answer:

The cost of 60 pens is ₹ 360

Step-by-step explanation:

Given information,

The cost of 15 pens is ₹ 90

We have to find out the cost of 60 pens

As,

The cost of 15 pens = 90

The cost of 1 pen = $\frac{the \: cost \: of \:15\: pens }{15}$

The cost of 1 Pen $= \frac{90}{15}$

By dividing 90 by 15 we get

The cost of 1 pen = 6

The cost of 60 pens = The cost of 1 pen × 60

The cost of 60 pens = $6 \times 60$

The cost of 60 pens = $360$

Hence,

The cost of 60 pens is ₹ 360
