Select a proper o

Answer :

We have been given that,

Z – M = 2.5


M = Z – 2.5 …(i)


And …(ii)


Here, Z = Mode,


M = Median


&


So, by empirical relationship we have,


Mode = 3 (Median) – 2 (Mean)



Putting equations (i) and (ii) in the above equation, we get


Z = 3(Z – 2.5) – 2×20


Z = 3Z – 7.5 – 40


3Z – Z = 40 + 7.5


2Z = 47.5



Z = 23.75


Thus, option (c) is correct.
