Reasoning - Logical Deduction and Decision Making

  • Decision making questions test practical judgement; choose the option that solves the problem within rules and without harm.

  • Cause and effect: the cause must precede the effect; do not assume a cause if the statement only reports an event.

  • Course of action: a valid action must be feasible, relevant and sufficient to address the problem in the statement.

  • Critical reasoning: identify the premise and the conclusion; the assumption bridges them.

  • Strengthen/weaken questions: the correct option makes the conclusion more or less likely without adding new unrelated facts.

  • Logical sequence of words: arrange by time, size, hierarchy or process order (e.g., seed → sapling → tree).

  • Analogy with numbers: check squares, cubes, primes and their positions; 2:8 :: 3:27 is a cube relation.
