Direction: The following question consists of three statements numbered I, II and III. Decide whether the data given in the statements are sufficient to answer the question below. Among five friends P, Q, R, S and T, each studies in a different standard, viz. 3rd, 4th, 5th, 6th and 8th. In which standard does R study? I. Q studies in a standard which is an odd number. R is Q's senior but does not study in 8th standard. II. Only three students are senior to P. Q is senior to P but junior to R. III. S is not junior to T. A) Inadequate data B) Only II C) Only I and II D) Only I and III

1. Inadequate data
2. Only II
3. Only I and II
4. Only I and III

Correct answer: Only I and II

Solution

Statement I only tells us that Q is in an odd standard and R is senior to Q, but R could still be in more than one standard. Statement II gives that P has three seniors, so P is 5th; then Q is senior to P and junior to R, forcing R to be 8th. Hence, only I and II together are sufficient.
