Question

There are $42$ integers in a group. If there are $5$ times as many odd integers as there are even integers, how many numbers are even integers?

• A. $7$
• B. 6
• C. 5
• D. 9

Answer 1

Answer: (A)

$7$

Let numbers of even integers be $x$

Then numbers of odd integers are $5x$.

$\therefore x+5x=42$

$6x=42$

$\Rightarrow x=\frac{42}{6}$

$=7$
