For answering Q7 and Q9: (just as an example) is 25 closer to 5 or closer to 50?

In other words is "closest" in q7/q9 defined using the absolute or relative difference.

25/5 = 5 and 50/25=2 so 25 is closer to 50 than to 5 using relative difference, while using absolute distance, 25 is closer to 5 than to 50.

Hope the course staff can confirm which definition to use in answering the question.

Many thanks!
