Question

The sum of 3 consecutive multiples of 6 is given as 180. Find the numbers obtained by dividing those multiples by 2.

• A. $54,60,66$
• B. $18,20,22$
• C. $27,30,33$
• D. $9,10,11$

Answer 1

The correct option is C $27,30,33$

Let the multiples be $x-6,x,x+6$.
Given: Sum $=180$
Therefore, $x-6+x+x+6=180$
$\Rightarrow 3x=180\Rightarrow x=60$
Thus,the numbers are $60-6,60,60+6=54,60,66$
When divided by 2, we get $27,30,33$.
