Speaking Volumes (Posted on 2004-11-10) Difficulty: 3 of 5
In a group of students, 50 speak English, 50 speak French and 50 speak Spanish. Some students speak more than one language. Prove it is possible to divide the students into 5 groups (not necessarily equal), so that in each group 10 speak English, 10 speak French and 10 speak Spanish.

are they allowed to speak 3 languages?

if so then we'll have 50 kids in 5 groups, 10 in each group.  all of them will be tri-lingual :o)
