Solution

The correct option is B $10$
Here,
$4 \frac{1}{5} \times 3 \frac{1}{3} + ? = 20 % o f 120$
It can also be written as
$\frac{21}{5} \times \frac{10}{3} + ? = 24 \Rightarrow 7 \times 2 + ? = 24$
$\Rightarrow \frac{21}{5} \times \frac{10}{3} + ? = 24 \Rightarrow 7 \times 2 + ? = 24$
$\Rightarrow ? = 24 - 14 = 10$
