Reasoning: Data Sufficiency Set 2

Directions (1-10): In each of the following questions, a question is followed by two statements numbered I and II. Read both the statements and answer accordingly.

  1. In which direction is the starting point as compared to Tisha’s current position?
    I. She started walking and took two consecutive left turns after walking 3 km each and then she took a right turn and walked 3 km to reach to her destination.
    II. She walked for 3 km and then took a right turn. Again she walked for 3 km and now took a left turn. She again walked for 3 km and finally took a right turn to reach her destination.
    A) If the data in statement I alone is sufficient to answer the question.
    B) If the data in statement II alone is sufficient to answer the question.
    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.

    Option D
    Explanation:

    In neither statement, the starting or the ending direction is given. So cannot be determined.
  2. What will be the code of ‘fr’?

    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.

    Option C
    Explanation:

    Both statements contain codes having single word common.
    From statement I, ‘is’ is ‘fr’
    From statement II, ‘sitting’ is ‘fr’
  3. Of the five persons, A, B, C, D and E, who is sitting in the middle of row?
    I. E does not sit at the corner. B is the only neighbor of A.
    II. D who is facing North direction is sitting to the immediate left of C.
    A) If the data in statement I alone is sufficient to answer the question.
    B) If the data in statement II alone is sufficient to answer the question.
    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.

    Option E
    Explanation:

    We do not know the directions in which they are sitting.
    From statement I, there are two possibilities as
    A B _ _ _ / _ _ _ B A
    From statement II, we have
    D C _ _ _ / _ D C _ _ / _ _ DC _ / _ _ _ D C
    If we combine both statements, we get
    A B D C _ / A B _ D C
    OR
    D C _ B A / _ D C B A
    Now from statement I, E cannot be at corner
    so we are left with A B _ D C and D C _ B A
    now whatever the arrangement is, E is at middle.
  4. Who is the tallest person?
    I. A is taller than only one person and that person is not B
    II. C and D are shorter than B.
    A) If the data in statement I alone is sufficient to answer the question.
    B) If the data in statement II alone is sufficient to answer the question.
    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.
    View Answer
    Option D
    Explanation:

    We do not know the number of persons in the group from any of the statements, so cant be determined.
  5. How is Kavita related to Shubhank?
    I. Shubhank is the son of mother of Ravi’s daughter.
    II. Kavita is the only daughter of Ravi’s wife.

    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.
    View Answer
    Option E
    Explanation:

    From both the statements, we get that Shubhank is the son of Ravi and Kavita his daughter. SO Kavita is sister of Shubhank.
  6. What is the position of Kavya from the right end in a row of 40 students?
    I. Dev is 16th from the left end of row and is sitting exactly between Kavya and Sana.
    II. Keerat who is sitting 10th from the right end is sitting exactly mid-way between Kavya and Shalu, who is fourth from the right end.
    A) If the data in statement I alone is sufficient to answer the question.
    B) If the data in statement II alone is sufficient to answer the question.
    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.
    View Answer
    strong> Option B
    Explanation:
    From statement I, we don’t know that Kavya is left or right of Dev (whose position is known). Also we do not know that Dev is how many places away from both Kavya and Sana.
    From statement II, we know that Kavya is left of Keerat, because Shalu is at Keerat’s right. Also when Keerat is 10th from right and Shalu is 4th from right so there are 5 students between Keerat and Shalu. Now since Keerat is mid-way between both, so Kavya is 5 places to the left of Keerat and so we can find Kavya’s position.
  7. On which day does Isha visit temple?
    I. The first date of the month was Wednesday and Isha visited temple on 11thof that month.

    C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.
    View Answer
    Option C
    Explanation:

    From statement I, 1 was on Wednesday, so 11 will be on Saturday.
    From statement II, 3 days back was Friday, so when she visited was Monday.

    D) If the data given in both I and II together are not sufficient to answer the question.
    E) If the data in both the statements I and II together are necessary to answer the question.
    View Answer
    Option B
    Explanation:

    More eating does not mean that the person is heavier.
    Statement II clearly says that Pavan is heaviest of his 5 friends so was not selected.
  9. What will be the code of SHINE?
    I. If INSERT is codded as JMTDSS
    II. If REVIEW is codded as SDWHFV
