## Show Answer

Solution(By Apex Team)

In 300 kg of solution,
Percentage of sugar = 40%
∴ Sugar = $\Large\frac{300 \times 40}{100}$ = 120 kg
Let x kg of sugar be added.
Now, according to the question
$\begin{array}{l}\Large\frac{120+x}{300+x}=\frac{1}{2}\\
\Rightarrow240+2x=300+x\\
\Rightarrow2x-x=300-240\\
\Rightarrow x=60\mathrm{~kg}\end{array}$
