A student scored the following marks in 11 questions of a question paper :

3, 4, 7, 2, 5, 6, 1, 8, 2, 5, 7.

Find the median marks.

For the following set of numbers, find the median :

10, 75, 3, 81, 17, 27, 4, 48, 12, 47, 9, 15.

The median of the observations 11, 12, 14, (x - 2), (x + 4), (x + 9), 32, 38, 47 arranged in ascending order is 24. Find the value of x and hence find the mean.

The mean of the numbers 1, 7, 5, 3, 4, 4 is m. The numbers 3, 2, 4, 2, 3, 3, p have mean m - 1 and median q. Find (i) p (ii) q (iii) the mean of p and q.
