Directions: Read the following information carefully and answer the questions given beside.
 
A definite number of persons are sitting around a circular table facing towards the center. V sits fourth to the left of Q. Q is one of the immediate neighbors of R. Only three persons sit between P and R (from one side only). Only five persons sit between T and S when counted from the left of T. U sits second to the left of T. Only three persons sit between R and T (from one side only). Not more than four persons sit between V and U when counted from left of U. Only six persons sit between T and Q counted from one side only. V is not an immediate neighbor of T.

What is the total number of persons sitting around the circular table?
» Explain it
C
Total 10 persons are sitting around the circular table.

Hence option C is correct.

Final Arrangement:
 
 

Common Explanation:

Reference:

Only three persons sit between P and R (from one side only).

Only three persons sit between R and T (from one side only).

Inference:

On the basis of given hints following two cases can be prepared:

Case-1: When R is fourth to the right of P.

Case-2: When R is fourth to the left of P.
 
 
 

Reference:

V sits fourth to the left of Q.

Q is one of the immediate neighbors of R.

Inference:

Further two cases arise from the existing cases namely Case-1A and Case-2A.
 
 
    

Reference:

V is not an immediate neighbor of T.

U sits second to the left of T.

Only six persons sit between T and Q counted from one side only.

Inference:

Thus Case-2 and Case-2A fail as V is sitting adjacent to T in both these cases.

To satisfy the third hint, we will add place for two more persons towards the right of T in Case-1A and place for one person towards the right of T in Case-1.
 
 
 

Reference:

Not more than four persons sit between V and U when counted from left of U.

Only five persons sit between T and S when counted from the left of T.

Inference:

Case-1A fails to satisfy the first hint.

Thus, the final arrangement is obtained through Case-1.

D
R is seventh to the left of V.

Hence option D is correct.

Four of the following five are alike in a certain way and thus form a group. Which of the following does not belong to the group?
» Explain it
E
Only 'QR' is the pair where both the persons are immediate neighbors. In other pairs both the persons are not adjacent to each other.

Hence option E is correct.
