Solution

Forming algebric expression:
Lets say $h$ is number of hours Adi studied.
An algebraic expression that represents the situation and evaluates when $h = 8 .$
If Adi studied for three more hours $h + 3$ .
Now $h + 3$ is the required algebraic expression.
If he study $8$ house a day, then we get
$\begin{array}{rcl} \Rightarrow & h + 3 = 8 + 3 \\ = & 11 \end{array}$
Therefore, the algebraic expression for the given situation is $h + 3$ and Adi studies $11$ hours in total.
