Question

the mean of 5 numbers is 29. find the sum of these five numbers
​

Answer 1

Answer:

Hi ,

we know that ,

Mean = ( sum of the observations )/(number of observations )

according to the problem given,

1 )mean of 5 numbers = 29

sum of 5 numbers = 5 × 29 = 145 ---( 1 )

if one number excluded the new mean = 29 - 2

= 27

number of observations = 4

sum of the 4 observations = 4 × 27

= 108---( 2 )

The excluded number = ( 1 ) - ( 2 )

= 145 - 108

= 37

I hope this helps you.
