Answer 1

Answer:

${\tt{\red{\underbrace{\bold{\huge{Answer:}}}}}}$

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 :)
