In these questions, a question is given followed by information in three statements. You have to consider the information in all the three statements and decide the information in which of the Statement(s) is not necessarily required to answer the question and therefore can be dispensed with. Indicate your answer accordingly.
How many students from Institute ‘A’ got placement ?
I. Number of students studying in Institutes A and B are in the ratio of 3:4 respectively,
II. Number of students who got placement from Institute B is 120% of the number of students who got placement from Institute A.
III. 80% of the students studying in Institute B got placement.
From I & II : Let number of students studying in institute A = $$3x$$
=> Students studying in institute B = $$4x$$
We got no relation between the number of students and students who got placed.
Similarly, by using statement III, we face the same problem.
Thus, this question cannot be answered even with the information in all three statements.
