Step-by-step explanation:

Given information,

the cost of 15 book is ₹ 645 .

We have to find out the cost of 29 book

As,

The cost of 15 book = 645

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

The cost of 1 book $= \frac{645}{15}$

The cost of 1 book is ₹ 43 .

The cost of 29 book = The cost of 1 book × 29

The cost of 29 book = $43 \times 29$
