S consist of the numbers

Lets arrange the number in ascending order

-2,1,5,8....and n

Stmt I

if n is negative, median = 1

Insuff

Stmt II

if n = 3 median = 3 but if n = 10, median = 5

Insuff

Stmt I&II

1 < median < 5

so n will be between 1 and 5, since only then can we get a median between 1 and 5

sacx! Please read the lines mingled with your solution:

Lets arrange the number in ascending order

-2,1,5,8,n

You assumed n to be the greatest here. Why?

Stmt I

n could be negative or it could between 0 and 5. in both cases we will get median 5

How can you support this phrase? How can 5 be the median if n < 0?

Insuff

Stmt II

if n = 3 median = 3 but if n = 10, median = 5

Insuff

Stmt I&II

1 < median < 5

so n will be between 1 and 5

You must have mentioned the message of the merger that n is in fact the median, before concluding “so n will be between 1 and 5”.

do you agree?
