Question

If 4,4,2,3,5,5,4,5,x in this the mean mode median is same and then find the value of "x"

Answer 1

Given: mean= median= mode

total no.= 9(it is odd)

Median= n+1/2 = 9+1/2 =10/2 =5

Mean= sum of all no./total no.

5 = 4+4+2+3+5+5+4+5+x/9

5 = 32+x/9 =》9×5 =32+x =》45 =32+x =》45-32 = x

therefore x=13.

hope i am right.

Answer 2

We know that,

Mode = 3 median - 2 mean

let mode is 4

4 = 3(4) - 2x

4 = 12 - 2x

2x = 12 - 4

2x = 8

x = 8 / 2

x = 4

OR

if mode is 5 then

Mode = 3 median - 2 mean

5 = 3(4) - 2x

5 = 12 - 2x

2x = 12 - 5

2x = 7

x = 7/2

x = 3.5

HPE THIS WILL HELP YOU!!!!!
