What is the number that could be added to Set G without changing its median?
As the number of elements in G are even, the median of G = (9 + 11)/2 = 20/2 = 10

Now, if we add any value less than 10 to G, the median of G will be 9.
And, if we add any value more than 10 to G, the median of G will be 11.

Only if we add 10 to G, the median will remain unchanged.
