Reasoning and Mental Ability: Verbal, Analytical and Non-Verbal
Reasoning and Mental Ability rewards pattern recognition rather than calculation. BPSC mixes verbal items (series, analogy, coding-decoding, blood relations, direction sense, ranking, syllogism) with analytical puzzles (seating arrangement, scheduling) and non-verbal items (mirror and water images, figure series, paper folding, counting figures).
Rules that save time
- Alphabet positions: remember E = 5, J = 10, O = 15, T = 20, Y = 25, then step off from these anchors.
- Opposite letters sum to 27 (A with Z, B with Y), which halves the work in letter-pair questions.
- In direction sense, draw the path on paper; the shortest distance is found with Pythagoras.
- In syllogism, draw Venn diagrams; 'some A are B' converts to 'some B are A', but 'all A are B' does not convert.
- In coding, test letter-wise shifts before word-level substitutions.
Worked example
If MANGO is coded as NBOHP, how is GRAPE coded? Reasoning: M→N, A→B, N→O, G→H, O→P, so each letter moves forward by one position. Applying the same shift to GRAPE gives H S B Q F, that is HSBQF.
Traps that cost marks
Turning left and right relative to the person's facing direction rather than to the page; treating 'possibility' conclusions as invalid when they are valid; assuming data not stated in the puzzle; and over-investing in one seating arrangement while easy series questions remain unsolved.
