Q10 of 43 Page 293

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=


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.
