# Select a proper option (a), (b), (c) or (d) from given options and write in the box given on the right so that the statement becomes correct:

If M = 15, = 10, then Z=

A. 15

B. 20

C. 25

D. 30

Answer :

Given that,

M = 15

So, by empirical relationship we have,

Mode = 3 (Median) – 2 (Mean)

⇒

Putting given values in the above equation, we get

Z = 3(15) – 2×10

⇒ Z = 45 – 20

⇒ Z = 25

**Thus, option (c) is correct.**
