Slot -1 – Quantitative Aptitude – Modern Maths – Set Theory – If among 200 students

If among 200 students, 105 like pizza and 134 like burger, then the number of students who like only burger can possibly be?

a) 96
b) 23
c) 93
d) 26

Answer: c) 93

Solution:
Surplus = 105 + 134 – 200 = 39
So there will be minimum 39 students who will like both pizza and burger.  And maximum number of students who like both can be 105.
So minimum number of students who like only burger = 134 – 105 = 29
And maximum number of students who like only burger = 134 – 39 = 95
Thus from given option only option c) 95 can be the number of students who like only burger.
