Question

Find the medain of 34, 32, x, x+1, 19, 15, 11 where x is the mean of 10, 20, 30, 40, 50.

Answer 1

mean x=30 {10+20+30+40+50=150} {150/5=30}
median x+1=31

Answer 2

x = Mean of 10, 20, 30, 40, 50
So, x = (10+20+30+40+50)/5 = 150/5 = 30

Arranging the terms in ascending order

11, 15, 19, 30, 31, 32, 34

The middle most value of the data is 30
Therefore, Median = 30
