Question

Median of the following number 40,38,2x+10,2x+1,15,11,8,5 arranged in descending order is 29.Find value of x.

Answer 1

Step-by-step explanation:

Given  

Median of the following number 40,38,2x+10,2x+1,15,11,8,5 arranged in descending order is 29. Find value of x.

Here n = 8

So median = average of 4th and 5th given observations

29 = 2x + 1 + 15 / 2

29 x 2 = 2x + 16

58 = 2x + 16

2x = 58 – 16

2x = 42

So x = 21
