Back to your mathematical roots

Over the weekend, someone posed this problem to me and wanted my help in solving it. It didn't take me too long to figure it all out. It was fun solving and reminded me how much I love solving such problems.

Here is the problem:

There are 400 students in a school. 180 take Spanish, 160 take Chinese and 160 take Latin. 60 take Spanish and Latin, 70 take Latin and Chinese and 60 take Chinese and Spanish. 50 take none. How many take all three?
