Out of a group of 50 students taking examinations in Mathematics, Physics, and
Chemistry, 37 students passed Mathematics, 24 passed Physics, and 43 passed
Chemistry. Additionally, no more than 19 students passed both Mathematics and
Physics, no more than 29 passed both Mathematics and Chemistry, and no more than
20 passed both Physics and Chemistry. What is the maximum number of students who
could have passed all three examinations?
