the mean of six numbers is 18. if one number is 23, what is the mean of the other 5 numbers.

mean = sum of six numbers / total number

so,

18 = sum of six numbers / 6

one number is 23 in that six numbers so,

18 = (23 + sum of other five numbers )/6

108 = 23 + sum of other five numbers

sum of other five numbers = 85...............................

now the mean of other five numbers = sum of other five numbers / 5

=85/5

=17........................

SO ANSWER IS mean = 17....................

hope you understood...please message if you have any doubts...thank you
