Option ( d ) is correct.


Explanation :

_______________________

We know that,


If mode = z , median = M ,


Mean = x


Than


z = 3M - 2x

_______________________


x = 21.44 , z = 19.13


3M = z + 2x


=> 3M = 19.33 + 2 × 21.44


=> 3M = 19.33 + 42.88


=> 3M = 62.01


=> M = 62.01/3


=> M = 20.67
