Given:
Numbers : X, 20, 2X+ 6, 2X+9, 40, 45, 52
Median of numbers = 29
To find :
The values of X, 2X+ 6 and 2X+9
Calculation:
The total number of given numbers are 7, as it is odd the middle term will be the median of the numbers i.e, 2X+9 will be the median
=> 2X+9 = 29
=> 2X = 20
=> X = 10
The values of X, 2X+ 6 and 2X+9 are
=> X = 10
=> 2X+6 = 2(10)+6 = 26
=> 2X+9 = 2(10)+9 = 29
The values of X, 2X+ 6 and 2X+9 are 10, 26, 29 respectively
