Answer 2

Answer: 1.8 m

Step-by-step explanation:

The original height is taken as 100 % , since the height increased by 20 % , this means that the new height is 120% of the original height. That

120% of 1.5

which is

$\frac{120}{100}$ x 1.5

1.5 could be written as 15/ 10 in fraction , so we have

$\frac{120}{100}$ x $\frac{15}{10}$

= $\frac{6}{5}$ x $\frac{15}{10}$

= $\frac{18}{10}$

= 1.8

Therefore Arnav is 1.8m today
