(1) At least 80% of the students, study either Mathematics or English or both
(2) The total students in the School is 200.
Solution:
- We have only been given the max. possible number of students for 2 criteries i.e. students who study Math and students who study both Math and English.
Statement 1.
The total students at the school will include, (students who study only math) + (students who study only english) + (students who study both) + (students who study none) = Total
We need the max for number of students who study neither but the value for total students is unknown
So statement 1 is insufficient
Statement 2.
We are given the total number of students but no other information
Clearly insufficient
Statement 1+2
Statement 2 gives exactly what statement 1 is missing. When we combine both, we have a definite answer.
IMO Correct answer is C

I dont see why 2 alone does not give you the answer.
The stem only sets out the maximum value so my distribution could totally look like this!
Bunuel care to weigh in?
