Ten observations written in descending order are 45, 34, 32, 30, 2x - 13, x + 1, 17, 15, 14 and 8. If the median is 24, then find 'x'.

Correct option is C

Median 24
The data are 45, 34, 32, 30, 2x - 13, x + 1, 17, 15, 14, 8
=>n=10
Median =$$\frac{ [(n/2)th term + (n/2 + 1)th term]}{2}$$​
24 =$$\frac{ [(10/2)th term+ (10/2 + 1)th term]}{2}$$​
=>24 = $$\frac{[5th term + 6th term]}{2}$$​
24=(2x-13 + x + 1)/2
24$$\times$$​2 = (3x-12)
3x =48+ 12
=>x= 60/3
x= 20
