Question

If half a number when added to the same number gives 120, then find the number.

• A. 100
• B. 80
• C. 60
• D. 40

Answer 1

The correct option is B

80

Let the number be x.

Half of the number = $\frac{x}{2}$

According to the question,

$\frac{x}{2}+x=120$

$\Rightarrow \frac{3x}{2}=120$

$\Rightarrow x=\frac{120\times 2}{3}$

$\Rightarrow x=80$
