Question

Is 500 the average (arithmetic mean) score in the GMAT?
A. Half of the people who take the GMAT score above 500 and half of the people score below 500.
B. The highest GMAT score is 800 and the lowest score is 200.

• A. The question can be answered by one of the statements alone but not by the other.
• B. The question can be answered by using either statement alone.
• C. The question can be answered by using both the statements together, but cannot be answered by using either statement alone.
• D. The question cannot be answered even by using both statements together.

Hint:

The average score needs the total sum of scores divided by the total number of participants, not just the range of scores.

Answer 1

The Correct Option is C

Statement A tells us that half the people who take the GMAT score above 500 and half below 500. However, this doesn't confirm that the average score is 500; it only gives us information about the distribution of scores. Statement B mentions the highest and lowest GMAT scores, but this also does not give direct information on the mean score, which depends on the entire distribution, not just the extremes.
