Question

One third of a number added to itself gives $8$. Find the number.

Answer 1

Let the required number be $x$

Then, one third of number $=\frac{x}{3}$

$\frac{x}{3}+x=8$

$\Rightarrow \frac{x+3x}{3}=8$

$\Rightarrow x+3x=8\times 3$

$\Rightarrow 4x=24$

$\Rightarrow x=\frac{24}{4}$

$\Rightarrow x=6$

$\therefore$ Hence, the required number be $6$.
