    Question

    Each of the questions given below has one question and two statements marked I and II. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.

    How many students from Institute R got placement?

    I. The number of students studying in Institute Q and R are in the ratio of 5:7. II. 55% of the students studying in institute R got placement.
    A If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    B If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    C If the data either in statement I alone or in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data even in both the statement I and II together are not sufficient to answer the question Correct Answer Incorrect Answer
    E If the data in both statement I and II together are needed to answer the question. Correct Answer Incorrect Answer

    Solution

    From I and II, Let the number of students in institute Q be 5x and that in institute R be 7x. Then, 55% of students in R 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.
