Question

If a laser printer can print $x$ pages per minute, calculate the time in minutes, in terms of $x$, would it take the laser printer to print a $100-page$ document.

• A. $100x$
• B. $100-x$
• C. $100+x$
• D. $\frac{x}{100}$
• E. $\frac{100}{x}$

Answer 1

The correct option is E $\frac{100}{x}$

The laser printer can print $x$ pages per minute.

$\therefore$ time required to print $1$ page $=\frac{1}{x}$ minutes.

So, to print $100$ pages, it would require $100\times \frac{1}{x}=\frac{100}{x}$

Hence, option E is correct.
