Q. 10 E5.0( 1 Vote )

# 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. 15B. 20C. 25D. 30

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.
