In each of these questions, one question is given followed by data in three statements I, II and III. You have to study the question and the data in statements and decide the question can be answered with data in which of the Statements and mark your answer accordingly.
How many students passed in first class?
Statements: I. 85% of the students who appeared in examination have passed either in first class
or in second class or in pass class.
II. 750 students have passed in second class.
III. Number of students passed in pass class is 28% of those passed in second class.
Clearly, each statement alone is not sufficient.
And since we do not know the total no. of students in the class, we cannot determine the number of students passed in first class.
Thus, all statements combined together are not sufficient.
