Question

in a class of 50 students 35 like physics 30 like mathematics and 3 like none of the subject how many student like only physics

Answer 1

Answer:But, here we go. If there are 50 students and 3 like neither math or physics, then 47 of them either like one or both of the subjects. Adding up the 30 and 35, we get that 65 of the students like the two subjects collectively. Well that’s not right. We have overcounted the 65–47=18 students who like both subjects. Thus, 35–18=17 students only like physics.

Step-by-step explanation:

50-3=47

30+35=65

65-47=18

35-18=17

Answer 2

35 students like physics. With the given information we can deduce that 35 like physics.We don't know the interests of the other 2 students. So we assume that 35/50 students like physics or 70 percent of students.
