Aptitude / Reasoning
Aptitude and Reasoning in UP B.Ed JEE tests pattern detection, logical deduction, and spatial/verbal reasoning rather than memorised facts. Typical items include series, analogies, coding-decoding, blood relations, direction sense, syllogism, clocks/calendars, and seating arrangement.
Core rules
- Series: check differences, ratios, squares/cubes, alternating patterns, and letter positions.
- Coding: write the alphabet with positions; test shift or reversal on each letter.
- Blood relations: draw a family tree; use gender labels only when stated.
- Direction: fix north and track each turn; use Pythagoras for shortest distance.
- Syllogism: follow the premises, not real-world truth; 'some' is not reversible.
- Clocks: angle = |30H - 5.5M|; calendars: odd days.
Worked example
A is B's mother. B is C's sister. C is D's father. How is A related to D? Reasoning: B and C are siblings, and A is their mother. C is D's father, so A is the father's mother. Answer: paternal grandmother. B is female because she is called sister; no gender is assumed for C beyond father.
Traps
- Assuming a person's gender from a role or name.
- Reversing 'A is the mother of B' in the final answer.
- Ignoring 'only', 'all', 'some', or 'none' in syllogism.
- Tracking left/right turns as fixed compass directions after a rotation.
- Picking the first number-series pattern without checking the next term.
- For seating, convert negative clues into a grid before drawing.
