Question:-
If the values of median and mode are 42 and 47 respectively, the value of Arthmatic mean can be :
Select one:
a. 38.5
b. 45
c. 39.5
d. 52
Given:-
median and mode are 42 and 47
To Find :-
value of Arthmatic mean
Solution:-
Option C
Explanation:-
When Mean, Median and Mode is given than we can use the empirical relation between them find the third one. The relation is :-
3median - 2mean = mode
Putting the values in the above formula
= 3 × 42 - 2 × mean = 47
= 2 × mean = 126 - 47
= 2 × mean = 79
= Mean = 79/2
= Mean = 39.5
Hence, Option c is correct :)
