Directions: Below question consists of a question followed by some statements. Study the following information carefully and decide which of the following statement is sufficient to answer the question
1. In persons – P, Q, R, S, T, U, and V are sitting in a row facing south. Who among the person sits second to the right of S?
I. Q sits second from the right end. Two persons are sitting between Q and R.
II. U sits fourth to the left of P.
III. Neither T nor U sits adjacent to R.
A. Both II and III
B. Both I and III
C. All I, II, and III
D. Only I
E. None
Sol:
From I, II, and III:
Q sits second from the right end. Two persons are sitting between Q and R. U sits fourth to the
left of P. Neither T nor U sits adjacent to R.
Based on the above given information we have:
Since, the exact position of S is not known. Hence, all statement I, II, and III are not sufficient.
2. Eight boxes – B1 to B8 are kept one above the other but not necessarily in the same order. Consecutive numbered boxes are not kept together. Which of the box is kept immediately below B5?
I. Box B5 is kept third from the bottom. Three boxes are kept between B5 and B2, which is kept immediately above B4.
II. Three boxes are kept between B6 and B1, which is kept two places above B3.
III. One box is kept between B1 and B4.
A. Both II and III
B. Both I and II
C. All I, II, and III
D. Only I
E. None
Sol:
From I and II:
Box B5 is kept third from the bottom. Three boxes are kept between B5 and B2, which is kept immediately above B4. Three boxes are kept between B6 and B1, which is kept two places above B3.
Based on the above given information we have:
Clearly, B3 is kept immediately below B5.
Hence, both statement I and II are sufficient.
3. Eight persons – A, B, C, D, E, F, G, and H are sitting on a circular table facing the center. Who among the person is facing D?
I. G sits third to the right of E, who sits immediate left of the one who sits facing H. Neither B nor C sits adjacent to H.
II. A and B are sitting together.
III. One person sits between F and G, who sits immediate right of C.
A. Both II and III
B. Both I and II
C. All I, II, and III
D. Only I
E. None
Sol:
From I, II, and III:
G sits third to the right of E, who sits immediate left of the one who sits facing H. Neither B nor C sits adjacent to H. A and B are sitting together.
One person sits between F and G, who sits immediate right of C.
Based on the above given information we have:
Clearly, E sits facing S.
Hence, all statements I, II, and III are together sufficient.
