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.
In a circular seating arrangement, 6 people A, B, C, D, E, F sit around a table. B sits opposite to E. A is to the immediate right of B. C is between D and F. Who sits to the immediate left of D?
Answer: C
In circular arrangement with 6 people: B opposite E means 3 seats apart. A right of B. C between D and F means F-C-D or D-C-F. Testing positions: B at 1, A at 2 (right), E at 4 (opposite). Remaining D,C,F for 3,5,6. If D at 3, C at 5, F at 6: C is left of D. If D at 6, C at 3, F at 5: F is left of D. Checking constraint 'C between D and F': F(6)-C(5)-D(3) works in circular. Left of D(3) is C(5).
