The mean of 6 numbers is 32. If one of the numbers is excluded, the mean reduces by 2. Find the excluded number.

42

Step-by-step explanation:

Mean = Sum of numbers / Total numbers

Sum of 6 numbers = 32 x 6

= 192

If one number is excluded the mean reduce by 2. so it becomes 30

Sum of 5 Numbers = 5 x 30

=150

Therefore the excluded number is

= 192 - 150

= 42.
