Question

The average of six numbers is 4. If the average of two if those numbers is 2,what is the average of the other 4 numbers?

Answer 1

Answer: Average of other 4 numbers =5

Explanation:

Sum of n numbers = Average of n numbers x n

Given: Average of 6 numbers =4

so sum of 6 numbers = 6x 4 = 24

Average of 2 numbers = 2

Sum of 2 numbers = 2 x 2 =4

Sum of rest of 4 numbers = sum of 6 numbers - Sum of 2 numbers

= 24-4

=20

Average of 4 numbers =
`(20)/(4)`

i.e. Average of 4 numbers =5
