Question

115. In a class of 50 students, 30 study Hindi, 25 study English
and 11 study both Hindi and English. The number of
students who do not study any of these two languages is :
(a) 11
(b) 19
(C) 14
(D) 6​

Answer 1

Answer:

b 19 students don't study both the languages

Answer 2

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Number of students = 50

Number of students study Hindi = 30

Number of students study English = 25

Number of students study both = 11

So, we will use:

$n(H\cup E)=n(E)+n(H)-n(E\cap H)\\\\n(H\cup E)=30+25-11\\\\n(H\cup E)=44$

Now, the number of students who do not study any of these two languages would be

n(H∪E)'=n(U)-n(H∪E)=50-44=6

Hence, Option 'D' is correct.
