Find the median of the following:

Find the median of first $10$ prime numbers.

$15$ students secured the following marks in a test in statistics find the median marks.

$35, 28,13,17,20, 30,19, 29,11,10, 29, 23,18, 25,17$

Calculate the median from the following data,

Out of a total of $16$ observations arranged in ascending order, the $8^{\mathrm{th}}$ and $9^{\mathrm{th}}$ observations are $25$ and $27$ respectively. What is the median?

The median of following observations arranged in ascending order, 

$8, 9, 12, 18, (x+2), (x+4), 30, 31, 34, 39 \mathrm{is} 24$. What is $x$?

The following data have been arranged in ascending order:

$18,20,25,26,30,x,37,38,39,48$.

If the median of the data is $35$, find $x$.

If $48$ is replaced by $28$, find the new median.
