If the median of the distribution 10, 12,13, 16, x, 20, 25, 30 is 18,

1.	If the median of the distribution 10, 12,13, 16, x, 20, 25, 30 is 18, then thevalue of x is
Answer» Given data10, 12, 13, 16, x, 20, 25, 30 Median = 18 As total number of terms are 8 which is even. Hence median for given distribution= 1/2 [n/2 th term + (n/2 + 1)th term] Hence,(16 + x) /2 = 1816 + x = 36x = 36 - 16 = 20 Therefore, value of x = 20

If the median of the distribution 10, 12,13, 16, x, 20, 25, 30 is 18, then thevalue of x is

Answer»

Given data10, 12, 13, 16, x, 20, 25, 30

Median = 18

As total number of terms are 8 which is even. Hence median for given distribution= 1/2 [n/2 th term + (n/2 + 1)th term]

Hence,(16 + x) /2 = 1816 + x = 36x = 36 - 16 = 20

Therefore, value of x = 20
