Question

In a survey of 600 students in a school, 150 students were found to be taking tea and 225 taking coffee, 100 were taking both tea and coffee. Find how many students were taking neither tea nor coffee?

Answer 1

Answer:

325

Step-by-step explanation:

Given total number of students = n(U) = 600

Number of students taking Tea = n(T)= 150

Number of students taking Coffee = n(C)= 225

Number of students taking both tea and coffee = n(T∩C) = 100`

Number of students either taking tea or coffee

n(T∪C) = n(T) + n(C) - n(T∩C)

= 150 + 225 - 100

= 375 - 100

= 275

Now Number of students neither taking tea nor coffee

= 600-275

= 325

Answer 2

Answer:

125 no of students

explaination-:

no of students-600

students taking tea-150

students taking coffee-225

students taking both-100

thus total=150+225+100

=475

therefore no of students taking neither coffee nor tea is=(600-475)

Required ans=125

hope so it helps u;)♡
