Question

if the median and mode of the data 8, 7, 2,
5,4,4, y, z,5,5,6,7,8 are x and y respectively.
If both z, y>x and x is an integer, then the
value of (x+y + z) cannot be equal to
a) 20
b)21
c) 22
d)23
please answer fast ​

Answer 1

Answer:

We have,

Mean =50 and Median =35

⇒

3

x+y+z

=50 and y=35

⇒x+z=115

But, z−x=55 (given). Therefore, x=30

Hence, y−x=35−30=5

Answer 2

Answer:We have,

Mean =50 and Median =35

⇒  x+y+z

=50 and y=35

⇒x+z=115

But, z−x=55 (given). Therefore, x=30

Hence, y−x=35−30=5
