Question

__

Answer 1

Given, 30 pages are left for reading.

Let the total pages of book $=x$

The fraction of book left for reading

$=1-\frac{4}{9}$

$=\frac{5}{9}$

So,

$\frac{5}{9}\times x=30$

$\Rightarrow x=30\times \frac{9}{5}$

$\Rightarrow x=54$

Hence, total number of pages in the book is 54
