Question

Ten observation are 6,14,15,17,x+1,2x-13,30,32,34,43 are written in ascending order . The median of the data is 24. Find the value of x. Plzzzzz tell the answer???

Answer 1

As the No: of observations is even , 
Median = [( n/2th observation) + (n/2)+1 th observation] ÷ 2
n/2 th observation = 5 th observation = x+1
(n/2)+1 th observation = 6th observation = 2 x-13
[x+1 + 2x -13] ÷ 2 = median
[x+1 + 2x -13] ÷ 2 = 24
(3x - 12) ÷ 2 = 24
3x - 12 = 24 × 2 
3x - 12 = 48
3x = 48 + 12
3x =  60
x = 60 ÷ 3 
∴ x = 20

Please mark as brainliest .

Answer 2

Answer: when no. Of data is even then median is( (n/2)th observations +. (n/2 +1)th observations )/2

When n is odd then median is

( n+1 /2)th observations

Here is n is even then

Median= (10/2)th observations +(10/2 +1)th observations /2

24 = 5th + 6th /2

48 = X+1 + 2x -13

60 = 3 X

X = 20
