Average of first 5 numbers =54 , Then sum of this 5 numbers = 54*5 =270.
The average of last 3 numbers = 52 . Sum of last 3 numbers = 52*3 = 156
The average of all 9 numbers =50 . The sum of all 9 numbers = 50*9 =450.
The required 6th number = sum of all 9 numbers -(sum of first 5 numbers + sum of last 3 numbers)
= 450 -(270+156)
= 450 - 426
=24
