3. Read the following information carefully and answer the questions given beside it. A certain number of persons sit around a square table such that nobody sits at the corner and not more than 4 persons sit around each of the sides. Information about a few persons is given and all the persons face towards the center. Only 4 persons sit between P and T, who is on the immediate left of Q. S is sixth to the right of U. R is at a gap of two persons from U, who is adjacent to T. Only one person sits between R and V, who is third to the right of S. How many such persons sit around the table about whom no information is given?

14

7

9

10

There are 7 such persons who sit around the table though no information is given about them.

Hence option B is correct.

Final Arrangement:

Common Explanation:

Reference:

S is sixth to the right of U.

R is at a gap of two persons from U, who is adjacent to T.

Only 4 persons sit between P and T, who is on the immediate left of Q.

Inference:

Following two cases are possible with respect to the given hints.

Reference:

Only one person sits between R and V, who is third to the right of S.

Inference:

Thus Case-1 fails to satisfy the given hint.

5. Study the information given below and answer the questions based on it. Eight persons A, B, C, D, E, F, G, and H are sitting in a circular arrangement and facing the center and after some time they are sitting in a straight line and facing north direction, not necessarily in the same order. B is 3^rd to the right of A in circle and 2^nd to the left of A in a straight line. H sits opposite to B in a circle. H is 2^nd to the right of D in a straight line. C is 3^rd to the left of H in a circle. D is the neighbor of A in a straight line. The one who is 2^nd to the right of A in a straight line is also 2^nd to the left of A in a circle. E is 3^rd to the left of F in the circle. At least 3 persons are sitting between E and F in the straight line but none of them at any ends. One person sits between B and C in the straight line. F is not a neighbor of H in the circle. G and E are not neighbors in both arrangements. The one who is opposite to D in the circle is not a neighbor of D in a straight line. Who among the following is 3^rd to the right of G in circular?

D

E

C

A

D is 3^rd to the right of G.

Hence, option A.

B is 2^nd to the left of A in line. D is neighbor of A in straight line. H is 2^nd to the right of D in straight line.

At least 3 persons are sitting between E and F in straight line and none of the at any ends.

One person sits between B and C in straight line. So Case 1C and Case 1D is rejected. G and E are not neighbors in both arrangements. So Case 2B is rejected.

B is 3^rd to the right of A in circular. C is 3^rd to the left of H in circular. The one who is 2^nd to the right of A in straight line also 2^nd to the right of 2^nd to the left of A in circular. So either F or E in circular is 2^nd to the left of A in circular. F is not neighbor of H in circular. So E is 2^nd to the left of A in circular then case 2A is rejected. E is 3^rd to the left of F in circular. G and E are not neighbors in both arrangements then G is immediate right of F and D is immediate left of E in circular. The one who is opposite to D in circular is not neighbor of D in straight line so case 1B is correct.

Here is the final arrangement:

Explanation

D is 3^rd to the right of G.

Hence, option A.

B is 2^nd to the left of A in line. D is neighbor of A in straight line. H is 2^nd to the right of D in straight line.

At least 3 persons are sitting between E and F in straight line and none of the at any ends.

One person sits between B and C in straight line. So Case 1C and Case 1D is rejected. G and E are not neighbors in both arrangements. So Case 2B is rejected.

B is 3^rd to the right of A in circular. C is 3^rd to the left of H in circular. The one who is 2^nd to the right of A in straight line also 2^nd to the right of 2^nd to the left of A in circular. So either F or E in circular is 2^nd to the left of A in circular. F is not neighbor of H in circular. So E is 2^nd to the left of A in circular then case 2A is rejected. E is 3^rd to the left of F in circular. G and E are not neighbors in both arrangements then G is immediate right of F and D is immediate left of E in circular. The one who is opposite to D in circular is not neighbor of D in straight line so case 1B is correct.

Here is the final arrangement:
