Question

Eddie can type 9 pages for a book in 40 minutes. If he keeps typing at the current pace, then the number of pages he can type in 2 hours is pages

• A. 36
• B. 27
• C. 30

Answer 1

The correct option is B 27

Eddie can type $9$ pages in $40$ minutes.
Then, Let Eddie can type $x$ pages in 2 hours or 120 minutes.

$\Rightarrow 9:40::x:120$

$\Rightarrow \frac{9}{40}=\frac{x}{120}$

Using cross multiplication

$9\times 120=40\times x$
$\Rightarrow x=9\times 3=27$ pages
