are distinct integers, which one is the median?
(1)

.
(2)

d>e

Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.
Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient
Either statement BY ITSELF is sufficient to answer the question.
Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

Solution:

Statement (1) tells us nothing about

e

and

d

.
Statement (2) tells us nothing about

a, b

and

c

.
Try to plug in some numbers, take:

a=3, b=7, c=1, d=9

and

e=8

. The median in that case is 7. Try other numbers,

a=8, b=15, c=6, d=10

and

e=9

. The median is 9 .
First the median was

b

, then the median was e. More sufficient data is required to answer the question.
