Every month we will give you a math/statistics brain teaser that lets you test your knowledge with a fun problem.
 This Month's Challenge: Job Applications
There are 100 people applying for a job that requires both a science and business background. 12 have no experience in either field. 64 have a science background and 80 of the applicants have a business background. How many of the applicants have a background in science and business?

The Answer!
56.
Since 12 have no background in either field, we have 88 applicants who have some experience in one area or the other. Of 88, 64 of them have a science background, which means 24 of this group don`t have a science background (88 - 64 = 24). 80 people have a business background, which means 8 out of the 88 don`t have a business background. 28 +8 = 32 people who have no background in either; so 88 -32 = 56 people who have both science and math backgrounds.
Many of the ideas in these Teasers come from thoughts formed by some of the great mathematical/statistical geniuses in history. To learn more about them and to take a fun quiz to find out which famous mathematician through history most interests you, try our Mathematicians' Quiz.
