IBPS PO Reasoning: Puzzle Test questions with solutions

Q1. Seven persons B, H, I, L, M, R and S live in a seven-floor building (floor 1 is the bottom floor and floor 7 is the top floor). Statements: I. Only three persons live between M and I, and I lives below M. One person lives between B and L. L lives three floors above I. II. S lives on an odd floor, not the top or bottom floor. Two persons live between R and L. H does not live above M. Question: Who lives on floor 2?

1. If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
2. If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
3. If the data either in statement I alone or in statement II alone is sufficient to answer the question.
4. If the data in both statements I and II together are necessary to answer the question.

Answer: If the data in both statements I and II together are necessary to answer the question.

Statement I alone does not uniquely determine who is on floor 2, and statement II alone is also insufficient. When both statements are combined, the floor arrangement becomes constrained enough to answer the question. Therefore, both statements together are necessary.

Q2. Six persons P, Q, R, S, T and U were born in three different months: May, September and November, on two different dates, 9 and 16, not necessarily in the same order. - P was born after R but not on the same date as R. - The number of persons born before S is equal to the number of persons born after T. - Q and U were born in the same month. - T was born in a month having even number of days. - Two persons were born between R and T. Who was born on 16th November?

1. R
2. P
3. Either Q or U
4. U

Answer: Either Q or U

The clues create a fixed order of births across the six slots formed by month-date combinations. Because Q and U are in the same month and the other conditions constrain the relative positions of R, P, S, and T, the 16th November slot can only belong to either Q or U.
