Hint: Percent: Percent or percentage is used in mathematics as the number or ratio which is expressed as fraction of hundredth. And this is followed by the sign ‘%’. Percentage has no dimension. Hence it is called dimensionless. Every percentage variable has three possible unknown variables: percentage, part, base.

Complete step-by-step answer:
Given,
Let x% be 30 minutes of an hours
So, as we know that
$ \Rightarrow 1hour = 60\min utes$
Now
$ \Rightarrow \dfrac{x}{{100}} \times 60 = 30$
$ \Rightarrow \dfrac{{6x}}{{10}} = 30$
$ \Rightarrow 6x = 30 \times 10$
$ \Rightarrow x = \dfrac{{300}}{6}$
$ \Rightarrow x = 50$
So, the correct answer is “ 50 %”.
