ARNISON CO (PRE June Mock 2023)

Hi Sir, while checking for the answer of the question, I saw that the examiner’s approach and my approach are poles apart, however, my answer is correct.
What the examiner does is probably known to you. What I did was
i) Cash for share offer:

Calculated the New Wealth of Birks Co. (No of shares * Cash per Share) and compared it with the Old Wealth (Ve) , and calculated the Gain % based on that.

ii) Share for share offer:

Calculated the New shares to be issued to Birks Co (60m/5 * 4), added it to the Shares of Arnison Co, which gave the total no of shares in the new co. Then divided it by the Ve of New company to get the value per share.
Then I Multiplied the value per share by the number of shares of both companies (after acq), which gave me the Ve. And compared the new Ve to the Old Ve. Which Eventually gave the same answer as the examiner.

Is this approach correct? Would I get marks if I attempt it this way?
