Question

the mean of 8 numbers is 41. the mean of 2 of the numbers is 29.what is the mean of other 6 numbers

Answer 1

Let sum of 8 numbers be x

Mean = x/8

41=x/8

X= 328

Let the sum of 2 number be y

Mean = sum/no of number

29 = y/2

Y= 58

So later sum of other 6 number is sum of all except that 2 numbers

=X - Y

= 328-58

=270

So mean of other six numbers

= 270/6

=45

Therfore mean of other six numbers is 45

Hope it may help u!!!!

Answer 2

Mean = Total/ Number of numbers

=> Total = Mean×Number of Numbers

Therefore, for 8 numbers:
Total = 8×41 = 328

For 2 numbers:
Total= 2×29= 58

Therefore the total of other six numbers
= 328-58
=270
Therefore,
The mean of other six numbers= 270/6= 45
