n, 15, 12, 9, 20
What is the value of n in the list above?

(1) n> 12
(2) The median of the numbers in the list is 13.

OA: B

The statements are quite ambiguous to me. Anyone, please explain the solution to this problem. Thanks a bunch!

Statement 1: n > 12

Certainly not helpful. n can have any value under the Sun. Insufficient.

Statement 2: The median of the numbers in the list is 13.

Since the statement refers to the median, we must first arrange the given list in an ascending order.

The arranged list in the ascending order: 9, 12, 15, 20; let's leave n for the time being.

Since there are five numbers in the set, the median would be the middle-most number, i.e., the third number. We know that median = 13, which is not among the given four numbers, n must be 13. Sufficient.

Hope this helps!
