Question

If x = 15 and Z=30, then Median (M)=


(a) 45
(b) 15
(c) 20
(d) 25
​

Answer 1

Answer:

x = mean = 15

z = mode = 30

We know that:

3 Median = 2 Mean + Mode

=> 3 Median = 2(15) + 30

=> 3 Median = 30 + 30

=> 3 Median = 60

=> Median = 20

Answer: (c) 20

______________

Answer 2

Answer:

a. x=15 and z= 30 ,median= 2mean +mode/3 then 15x2+30/3 =30+30/3 =60/3= 20
