Question 40

How many students are there in the class?
I. There are more than 22 but less than 36 students in the class.
II. If students of the class are divided into groups each group has exactly 11 students.
III. There are more than 29 but less than 45 student in the class.

Solution

Using II, we know that there are 11k students in the class where k = 1, 2, 3,...
Using statement I, we know that 22 < 11k < 36 => Only possible value of 11k is 33
So, the question can be answered using I and II alone
