The mean age of 11 women in an office is 31 years old. The mean age of 6 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office?

30.2

Explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:

186

6

=

31

And we can do the same for the men:

116

4

=

29

And now we can combine the sum and count of the men and women to find the mean for the office:

186

+

116

10

=

302

10

=

30.2
