D.O None

Option D is the right answer.

Answer 2

Given,

Total students in hostel=200
Students like idli=50
Students like upma=75
Students like both idli and upma=35

To Find,

Students like neither idli nor upma.

Solution,

Here, out of 200 students

50likes idli, and 35 likes both idli and upma
So, students like only idli,

50-35=15

Then, 75 students like upma

So, students like only upma,

75-35=40

So the number of students who like neither idli nor upma is

200-(35+15+40)

=200-90=110

Hence, 110 students neither idli nor upma in hostel.
