**(i).** Seven students P, Q, R, S, T, U and V take a series of tests.**(ii).** No two students get similar marks.**(iii).** V always scores more than P.**(iv).** P always scores more than Q.**(v).** Each time either R socres the highest and T gets the least, or alternatively S scores the highest and U or Q scores the least.

**If S is ranked sixth and Q is ranked fifth, which of the following can be true ?**

** Option:**

**A.**V is ranked first or fourth.

**B.**R is ranked second or third.

**C.**P is ranked second or fifth.

**D.**U is ranked third or fourth.

**E.**T is ranked fourth or fifth.

**Answer: D . U is ranked third or fourth.**

** Justification:**

In terms of scores, we have :

V > P, P > Q i.e. V > P > Q.

If R scores the highest, we have R > ...... > T,

If S scores the highest, we have S > ...... > Q or S > ...... > U.

If S is ranked sixth and Q is ranked fifth, we have :

? > ? > ? > ? > Q > S > ?.

In the case, R will rank the highest and thus T will rank the least.

We have :

R > ? > ? > ? > Q > S > T.

Also. the roder V > P > Q will be maintained i.e. V and P will have second, third or fourth places. So, statements (a), (b), (c) and (e) cannot follow. Thus, (d) is the answer.
