Solution:

85. The correct relationship among Arithmetic Mean (AM), Geometric Mean (GM) and Harmonic Mean (HM) is

Correct Answer: (c) [GM]² = HM x AM
Solution:

Relationship Among
Arithmetic Mean (AМ),
Geometric Mean (GM) and

86. For a moderately skewed distribution, the value of mode is 10 and value of median is 20 Then the mean is

Correct Answer: (c) 25
Solution:

3 (median) = mode + 2 mean
Median = 20
Mode = 10
Mean = ?
⇒3 (20) = 10 + 2 mean
60-10= 2 mean
mean = 50/2 = 25
