From statement 1 AND 2 Alone we get nothing....
but Combining these two statements we get that 3<x<7
For all the values in this Limit the condition is satisfied...
Eg
3,5,7,10,x
IF X = 6
mean = 6.2 and median is 6..
----> mean > median

Hence Using Both statements we get a definite answer..

If x= 5, then mean = median. Not sufficient. What am i missing here?

If x= 5, then the mean = 6, not 5, while median = 5.

So if I combine both statements, I get definite values of x as 4,5,6.

But If I only consider statement 1 and consider the value of x to be 11, I get:
3,5,7,10,11
Mean=36/5=7.2
Median is 7.
So Mean>Median.

So Why exactly do we need statement 2 here?

Thank you in advance!

you just did not test all the possible cases. With x=10 => the Median now is 35/5=7, the Mean now is 7. With this case, 7=7 so you just cannot jump into conclusion that statement 1 is sufficient.
