  1. Who is taller among A, B, C, D, and E?
    I. D is shorter than B. A is shorter than only E.
    II. B is taller than only D. E is taller than A and C.
    Answer & Explanation
    (C) If the data either in statement I alone or statement II alone are sufficient to answer the question.
    Explanation:

    From I : A is shorter than only E, this means that A is taller than all B C and D, so E is tallest.
    From II : B only taller than D, so D is shortest, and B is second shortest, Now E taller than A and C both, So tallest of all.
  2. What is the distance between point A and point B?
    I. Point C is 10 m west of point A and point D is 10 m north of point A.
    II. Point B is 10 m south-east of point C. Point D is 20 m north-west of point B.
    Answer & Explanation
    (D) If the data given in both I and II together are not sufficient to answer the question.
    Explanation:

    From I : No relation between points A and B
    From II : In this since we don’t know the angles between sides of triangle forming with points ABD and ABC, AB cannot be determined.
  3. How is Shubham related to Shivani?
    I. Shubham is brother of Meenal. Shivani is niece of Preeti.
    II. Neeraj is Meenal’s uncle and Preeti’s brother
    Answer & Explanation
    (D) If the data given in both I and II together are not sufficient to answer the question.
    Explanation:

    Either statement cant give the answer.
    From both statements we get the relationship as Preeti is Neeraj’s sister but it cannot be clearly said that Shubham and Meenal are Preeti’s children or not and Shivani is Neeraj’s daughter, because there can be other siblings of Neeraj and Preeti also.

    Explanation:

    From I : ‘no one face’ is ‘om fo sop’

    Answer & Explanation
    (A) If the data in statement I alone is sufficient to answer the question.
    Explanation:

    From I: The position of both in a row can be known, so Meena’s position can be known.
    From II: Since total number of students is not known in this case, Meena’s position with respect to Ruby cannot be known.
  7. Who has secured less marks among A, B, C, D and E?
    I. D has secured less marks than only C and E.
    II. B secured more marks than A.

    From II : B’s marks more than A
    From both, order in descending is C/E, E/C, D, B, A

  8. On which floor is Shruti residing?
    I. In a 6 storeyed building (Ground floor is parking space), Rupa is on 4th floor. Shruti likes to reside only on even numbered floors. Reena is not on the topmost floor.
    II. Reena is two floors below Prateek who is 3 floors above Shruti.
    Answer & Explanation
    (E) If the data in both the statements I and II together are necessary to answer the question.
    Explanation:

    From I: 6 storeyed building has 2, 4 and 6 even numbered floors, out of which Rupa is on 4th, so Shruti is on either 2 or 6. Reena is not on 6 (top-most), but since it is not given Reena also stays on even numbered floor, nothing can be known about Shruti.
    From II : Prateek is 3 floors above Shruti, this means that Shruti will have to be at 1, 2 or 3 floor, so that Prateek is at 3 above Shruti’s floor.
    From both, Shruti is at 2nd floor.
  9. Aditya is facing which direction?
    I. Surbhi is facing east direction and if she turns to her right she will face Rahul.
