Show step-by-step solution:
1. In a group of students, 23 are taking Biology subject, 20 are
taking Physics, 8 are taking both Biology and Physics, 8 are taking
neither. How many students are in the group?
2. Barry and Peter jog around a 400-meter track-and-field oval
in opposite direction. Barry runs at the rate of 100 meters per
minute, while Peter runs at 150 meters per minute. If they start at
the same time and at the same point, after how many minutes will
they meet again for the third time?
