Question

Suppose that in the last few seconds you devoted to question 1 on your physics exam you earned 4 extra points, while in the last few seconds you devoted to question 2 you earned 10 extra points. You earned a total of 48 and 12 points, respectively, on the two questions, and the total time you spent on each was the same. If you could take the exam again, how—if at all—should you reallocate your time between these questions?

Answer 1

Answer:

If you could take the exam again, you should spend more time solving the question 2.

Step-by-step explanation:

In the last few seconds of each question, you gained:

4 extra points in question 1. These points are a small fraction of your question 1 score.

10 extra points in question 2. These points are a large fraction of your question 2 score.

You gained 6 extra points in question 2 from the extra time. These 10 extra points are also a large fraction of the question 2 score, while your question 1 score was already good enough. This means that if you could take the exam again, you should spend more time solving the question 2.
