Question

If x = 21.44 and Z = 19.13, then M = ......,select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.
(a) 21.10
(b) 19.67
(c) 20.10
(d) 20.67

Answer 1

option B 19. 67 is your answer

Answer 2

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
