Question 32 :If among 200 students, 105 like pizza and 134 like burger, then the number of students who like only burger can possibly be
Given that out of 200 students, 105 like Pizza and 134 like Burger
In order to find the possible number of students who like only Burger, we need to find the range between the minimum and maximum possible number of students
Minimum possible number of Students who like only Burger:
For this, we must try to optimize the Venn diagram in such a way that it has maximum intersection
No of Students who like only Burger = 134 – 105= 29
Maximum possible number of Students who like only Burger:
For this, we must optimize the Venn diagram in such a way that it has minimum intersection
We know that total number of Students = 200
So, Minimum number of students who like both = 105 + 134 – 200 = 39 students
Students who like Burger = 134
Max. no of Students who like only Burger = 134 – 39 = 95
So range => 29 ≤ n ≤ 95
From the options, only (D) 93 lies within range
The question is "If among 200 students, 105 like pizza and 134 like burger, then the number of students who like only burger can possibly be"
Choice D is the correct answer.
