It may be like this ,
z = 25 , x = 25 , Find M .
**********************************
By Empharical Formula :
If mode = z. median = M ,
Mean = x , then
z = 3M - 2x
Or
M = ( z + 2x )/3
*******************************
M = ( 25 + 2 × 25 )/3
=> M = ( 25 + 50 )/3
=> M = 75/3
=> M = 25
Therefore ,
Option ( a ) is correct
