Question

The mean height of a group of 10 runners is 166.8cm . The tallest person in the group is 169.9 cm. Calculate the mean height of the remaining 9 members.

Answer 1

Sum of the height of the all runners be x
So mean=166.8
x/10=166.8
x=1668
Sum of heights of all except the taller one
=1668-169.9
=1496.1
Reqd mean height=1498.1/9
=166.9

Answer 2

Answer:

166.9

Step-by-step explanation:

let the sum of the height of the all runners be x

So,

x/10 = 166.8

x = 1668

Sum of heights of all except the taller one

=1668-169.9

=1496.1

mean height of remaining 9 = 1498.1 / 9

=166.9
