Reasoning Ability
What is tested
Reasoning Ability in KVS TGT is largely skill testing under time pressure: series, analogies, coding–decoding, blood relations, direction sense, ranking, syllogism, seating arrangements, and non-verbal figures. The paper rewards pattern recognition and clean notation, not calculation speed alone.
Core rules
- Number series: check differences, then ratios, then alternating/prime/square patterns. Letter series: convert to positions (A=1 … Z=26) and look for shifts, reversals, or paired jumps.
- Coding: test a uniform shift first; if it fails, test position-wise rules and reversal.
- Blood relations: draw a family tree; use vertical links for generations and horizontal for siblings/spouses; never assume gender from a name.
- Direction: fix a compass, track left/right from the facing direction, and use Pythagoras for shortest distance.
- Syllogism: a conclusion must hold in every possible Venn arrangement; “some” does not imply “all”.
Worked example
If PEN is coded as QFO, what is INK? Reasoning: P→Q, E→F, N→O: each letter moves +1. Apply to I, N, K → J, O, L. Answer: JOL. If the options included “JOM”, it would test whether you shifted every letter or only the first two.
Traps
In seating, mixing “facing north” and “facing south” left/right; in ranking, forgetting to add or subtract 1 for total; in blood relations, reading “brother of my father’s only son” as uncle instead of father; in series, stopping at the first plausible rule without checking the next term.
