These questions are based on the following information. Each of six persons - Pavan, Raman, Kiran, Charan, Shravan and Rajan stay in a different floor of a six storied $\left(1^{\mathrm{st}}, 2^{\mathrm{nd}}, 3^{\mathrm{rd}}, 4^{\mathrm{t}}, 5^{\mathrm{t}}\right.$, and $6^{\text {th }}$ from bottom to top respectively) building. I. Raman stays above Kiran but below Charan. II. Pavan stays below Rajan but above Shravan. III. Kiran stays above Pavan but below Raman who stays above Rajan. Who stays in the $2^{\text {nd }}$ floor? (A) Pavan (B) Shravan (C) Rajan (D) Cannot be determined

Key Concepts

Logical Deduction

Logical deduction is the systematic process of reasoning from given premises to deduce inevitable conclusions. In puzzles involving ordering and ranking, it involves analyzing the clues provided, drawing inferences through transitivity and other logical operations, and eliminating impossibilities to arrive at the unique solution.

Constraint Satisfaction

Constraint satisfaction refers to the process of assigning values or positions to items in a way that all given conditions or rules are met. This concept is widely used in combinatorial problems and puzzles, where one must determine an arrangement that fulfills all imposed ordering relationships.

Transitivity

Transitivity is a key logical principle whereby if one element is ordered ahead of a second, and the second is ahead of a third, then the first is ahead of the third. This concept is crucial in puzzles where multiple comparative clues must be combined to develop a complete order.

Partial Ordering

Partial ordering involves arranging items based on relative comparisons that are not completely sequential at the outset but can be ordered by applying given constraints step by step. In many logical puzzles, establishing a partial order helps set up the relative positions of items or persons before determining their precise positions.
