We have to find percentage of $4\dfrac{4}{{20}}$
We can write it as $4\dfrac{4}{{20}} = \dfrac{{84}}{{20}}$
So you will think that how I have changed in fractional form, it’s simple
$\left( {4\dfrac{4}{{20}} = \dfrac{{20 \times 4 + 4}}{{20}}} \right)$that is denominator multiply by outer number and add numerator divide by denominator.
For finding percentage we will multiply by $100$, we get
$\dfrac{{84}}{{20}} \times 100 = 420\% $
Hence option ${\text{B}}$is the correct option.
Note:- Whenever you get this type of percentage question, the key concept of solving is simply convert it into fractional form or decimal form whichever is easy in that question do that and multiply by $100$you will get a percentage of that question.
