Question

The average of 5 quantities is 6 and the average of 3 is 8 what is the average of remaining two?( statistics question of chapter measures of Central tendency)

Answer 1

Answer:

3

Explanation:

Let the quantities be a,b,c,d,e.

Then

(a+b+c+d+e)/5 = 6

(a+b+c+d+e) = 30

Also,

(a+b+c)/3 = 8

a+b+c = 24

Hence d+e = 6

Their average= 6/2 = 3
