If it is known that at least 23 students were eligible for a Symposium on Chemistry, then the minimum qualifying marks in Chemistry for eligibility to Symposium would lie in the range?
Answer: Option
Explanation:
Since 66 students get 20 and above marks in Chemistry and out of these 21 students get 30 and above marks, therefore to select top 35 students in Chemistry, the qualifying marks should lie in the range 20-30.

Gap between 66 and 21= 45>23. So c is right.

Answer should be (D) as they have asked for minimum eligibility range, and question doesn't mention anything about explicitly about passing criteria so we should not assume any extra information.

Common Sense: Here they asked atleast (enough) 23 students.
Generally, We suppose to choose students who scored maximum marks. So, therefore 40 and above = 4 & 30 and above = 21.
And Hence, 21+4 = 25 the mid range. Option C is correct answer.
