In a class there are 200 students, atleast
140 students likes Maths, atleast 150 like
science and atleast 160 lice English.
What is the minimum number of students
who like all the three subjects.​

Answer 1

Answer:

180

Step-by-step explanation:

intersection=inter

n(AUB)=n(a)+n(b)+n(c)-n(a inter b)-n(b inter c)-n(c inter a)+n(a inter b inter c)

if we take max value for intersection of 2 quantities then we get

200=140+150+160-140-150-140+x

x=180
