There are three possibilities:

1) -2, n, 1, 5, 8

2) -2, 1, n, 5, 8

3) -2, 1, 5, n, 8

Statement 1 is will satisfy 2) and 3)
Statement 2 will satisfy 1) and 2)

Now clearly, 2) is satisfied by both 1) and 2). And from 2) you can easily say that 0<n<7

Therefore c)

Individually, either of the statement won't help you in in giving the conclusion that n lies within 0 and 7

We need to prove 0 < n < 7 ?

FACT : Median of the set of 5 numbers should be the value of 3rd number.

(1) The median of the numbers in set S is less than 5.
=> So n should be number before 5
=> n < 5, but NOT SUFFICIENT because we still need to prove n>0

(2) The median of the numbers in set S is greater than 1.
=> So n should be number after 1
=> n > 1, but NOT SUFFICIENT because we still need to prove n<7

Combining Statement-1 and Statement-2

=> 1<n<5, which also proves 0<n<7

So C.
