Choice (D) From the centered information, we know that 30 is the value for Column A. This is because:
We can pick numbers to figure out possibilities for Column B. It would be easy to make the 2 columns equal by either making all 5 integers 30 or by making them consecutive (even) with 30 as the middle value. If we eliminate 30 form the set in any way and still have the sum equal 150 (e.g.: 10, 10, 20, 40, 70), the median will be either less than (as in this case) or greater than 30. Anytime more than one result is possible the answer will be (D).
