ANSWER : T is ranked sixth

Explanation : . If R is ranked second and Q gets fifth position, then automatically S will get the top position and U the last. Now on the basis of the positions of R, Q, S, and U obtained so far V is positioned at third and P at fourth. Therefore, only option (4) i.e., position of T at the sixth position satisfies this order of ranking.

ANSWER : U is ranked third or fourth

Explanation : . If S is ranked sixth and Q is fifth, then automatically R will be ranked at first and T at seventh positions. Now one the basis of the positions of S, Q, R and T, only option (4), which positions U either third or fourth, can be valid.

ANSWER : S scores the highest

Explanation : . On the basis of the information (iii) and (iv), if (v) is ranked fifth, then P will be ranked 6th and Q seventh (the last position) and consequently, as per information (v), if Q gets last position, S will be positioned on top.

ANSWER : Fourth

Explanation : . If R gets the most, T will get the least. Now as per conditions, V is followed by P and P is followed by Q. Therefore, V carries two persons after him. Hence, V cannot be positioned lower than the 4th position.
