Question

For some data if M+x=22 and M-x=2 then z=?

Answer 1

M+x=22...(I)
M-x=2......(ii)
.________
2M=24
M=24/2
M=12
---------------
substitute m=12 in equation (I)
M+x=22
(12)+x=22
x=22-12
x=10

Answer 2

Answer:

27

Step-by-step explanation:

We know

M+X=44-----1

M-X=2--------2

M+X=44

M-X=2

--------------

2M = 46

M=23

Putting M =23 in ----1

M+X=44

23+X=44

X=44-23

X=21

RELATION BETWEEN MEAN, MEDIAN AND MODE IS :-

Z=3M-2X

Z=3(23)-2(21)

Z=69-42

Z=27
