In the following example, for 3rd question and 4th question why do we have to add (Stock price in three months - Current stock price) to put option profit?
Thank you in advance.

A hedged stock position means that you own the stock and an option to reduce the risk. For owning the stock, you pay $S_0$ but receive $S_T$ in 3 months. Similarly, your option costs $1.50$ but will give you $\max\{X-S_T,0\}$.
