Hi there,

I know exactly where this is from :) (BCG Casey Chatbot practice test)

You need to do a weighted average.

When company A and B merge, they will have 20% market share (think, 20 dollars).

That means Company A has 60% of the revenue of the combined company and Company B has 40%)…12/20 and 8/20.

To get the weighted average from this you take Company A's weight, so 4 (profit margin) times 60%, which equals 2.4.

You then add that to Company B's weight, so 3 times 40%, which equals 1.2

You add these two to get 3.6 et voila!
