Question

If $13$ is added to one-half of a certain number, the result is $37$. The original number is equal to

• A. $24$
• B. $40$
• C. $48$
• D. $61$

Answer 1

The correct option is C $48$

Let the original number is $x$

Then according to the question, we have

$\frac{x}{2}+13=37$

$\Rightarrow \frac{x+26}{2}=37$

$\Rightarrow x+26=74$

$\Rightarrow x=74-26$

$\Rightarrow x=48$

Therefore, the original number is $48$.
