Question

Robert reads 15 pages of the novel each day, and he finishes the book in 10 days. How many pages are there in the novel?

• A. 145
• B. 150
• C. 155
• D. 160

Answer 1

The correct option is B 150

Total number of days to finish the novel $=10$

The number of pages he reads each day $=15$

Let the total number of pages in the novel be $x$
$\therefore \frac{\text{Total number of pages in the novel}}{\text{Total number of days to finish the novel}}=\text{Number of pages he reads each day}$
$\Rightarrow \frac{x}{10}=15$

Multiply both sides by 10
$\Rightarrow \frac{x}{10}\times 10=15\times 10$

$\Rightarrow x=15\times 10\Rightarrow x=150$

Hence, Total number of pages in the novel is 150.
