Answer 2

Answer:

The cost of dozen book is ₹ 60 .

Step-by-step explanation:

Given information,

the cost of 25 book is ₹ 125 .

We have to find out the cost of dozen book

As,

The cost of 25 book = 125

The cost of 1 book = $\frac{the \: cost \: of \: 25 \: book }{25}$

The cost of 1 book $= \frac{125}{25}$

By dividing 125 by 25 we get

The cost of 1 book $= 5$

The cost of 1 book is ₹ 5 .

As ,

1 dozen = 12 substance

So, 1 dozen of books = 12 books

The cost of 12 book = The cost of 1 book × 12

The cost of 12 book = $5 \times 12$

The cost of 12 book = $60$

Hence,

The cost of dozen book is ₹ 60 .
