Question

(1) The median of the observations 11, 12, 14, 18, (x + 4), 30, 32, 35, 41 arranged in ascending order is 24. Find the value of x.
​

Answer 1

Answer:

11, 12, 14, 18, (x + 4), 30, 32, 35, 41

No. of terms are odd (9)

∴ Median = [(n + 1)/2]th term

= [(9 + 1)/2]th term

= 5th term

∴ Median = x + 4

and Given Median = 24

∴ x + 4 = 24

x = 20
