Question

If the sum of two consecutive even numbers is $312$, find the numbers.

• A. $155$ and $157$
• B. $155$ and $156$
• C. $156$ and $157$
• D. $154$ and $153$

Answer 1

The correct option is A $155$ and $157$

Let the two consecutive even numbers be $x$ and $(x+2)$.

Therefore, $x+x+2=312$

$2x+2=312$

$2x=312-2$

$2x=310$ ...(Divide both sides by $2$)

$\therefore x=155$

So, the numbers are $155$ and $157.$

So, option A is correct.
