ECGC PO sets 50 Reasoning Ability questions for 50 marks in the Online Examination: Objective Test, so it is worth planning your preparation around the topics below.
The puzzles and seating arrangements carry the most marks and take the most time, so the skill is choosing which set to attempt and which to leave. Clear the quick scoring topics — inequality, syllogism, coding-decoding, blood relations — first, then spend the remaining time on one or two puzzles you can actually finish.

Circular seating arrangement · solved example
Which of the following pairs are the immediate neighbours of H?
Solution
Fixing A and working clockwise, the seats run A, D, G, C, F, B, H, E. That order comes out as follows: D is immediately to A's left, and for someone facing the centre the left is the clockwise direction, so D is one seat clockwise of A. C is three seats clockwise of A, which leaves exactly one seat between D and C, and G takes it. B is two seats clockwise of C, and E is opposite C, which is four seats away. F must neighbour C, and the only free seat adjacent to C is the one between G and B. H takes the last seat. H sits between B and E, so those two are its neighbours. Note that H is the only person whose seat is never fixed by a clue directly; it is settled by elimination once the other seven are placed, which is often how the last person in a circular puzzle is found.
Classification · solved example
Four of the following five are alike in a certain way and form a group. Which is the one that does not belong?
Solution
Every number except 20 is a prime number, so 20 is the odd one out.
Analogy · solved example
4 : 64 :: 9 : ?
Solution
The rule is: each is the cube of the first. Applying it to 9 gives 729.
