Reasoning is the one section where practice changes your score fastest, because the question types repeat even when the surface changes. Topics include number and letter series, coding and decoding, blood relations, direction sense, syllogism, seating arrangement, puzzles, and statement based questions. Solutions show the diagram or table used to reach the answer, which is the part worth copying into your own method.

Six people sit around a circular table: F, G, H, I, J, K. G sits 2 seats to the right of F. H sits opposite to J. I is not adjacent to G. K sits to the left of F. Who sits between I and J (clockwise from I)?
Answer: C
In a circular arrangement with 6 seats: If K is to the left of F and G is 2 seats to the right of F, we get a relative positioning. H opposite to J means they are 3 seats apart. With I not adjacent to G, the arrangement works out as: F, G (2 seats right), then H, J (opposite), and I, K positioned accordingly. The person between I and J clockwise is H.
