Question

After reading $\frac{4}{9}th$ of a book, 30 pages are left. How many pages are there in the book?

• A. 54
• B. 36
• C. 24
• D. 60

Answer 1

The correct option is A

54

Let the total number of pages in the book be $x$.

$(\frac{4}{9}\times x)\text{pages are read}$

$\text{Remaining pages}=x–\frac{4x}{9}$
$=\frac{5x}{9}=30$$\Rightarrow 5x=30\times 9$
$x=54\text{pages}$
