GRE Quantitative Reasoning QUESTION #8110
Question 1

If the arithmetic mean of 5 consecutive integers is 12, what is the sum of the least and greatest of these integers?

  • $24$✔️
  • $14$
  • $12$
  • $11$
Correct Answer Explanation

For 5 consecutive integers, the mean equals the middle (3rd) integer. So the middle integer is 12.

The 5 integers are: $10, 11, 12, 13, 14$.

The least is 10 and the greatest is 14.

Sum $= 10 + 14 = 24$.
