You should use the data and your knowledge of Mathematics to choose the best possible answer. How many students from Institute N got placement? I. The number of students studying in Institute M and N are in the ratio of 5 : 7. II. 55% of the students studying in institute N got placement. Correct Answer If the data even in both the <strong>statement I and II together are not sufficient </strong>to answer the question and

From I and II,

Let the number of students in institute M be 5x and that in institute N be 7x.

Then, 55% of students in N got placement.

∴ 55% of 7x got placement.

So, neither I nor II is sufficient to answer the question because the exact number of students is not given.
