This question is tricky because there are multiple parts to answer so you have to think quick and read the question accurately.
The proportion of mixed consideration deals that were in New Zealand is:
1/4=25% (only the Alfost-Spacebar deal).
None were in the same year (one each was in 2007-2010).
The median stake taken was (choose the two middle numbers):
(76%+85%)/2=81%
Finally, the proportion that weren’t controlling stakes (where controlling stake is defined in the table as stakes that are in excess of 50%) was 0%; all stakes taken were greater than 50%.
