Solve Banking DI and Floor Puzzles in Under 3 Minutes
For SBI PO and IBPS PO, Reasoning and Quantitative Aptitude are gatekeeper sections. Most aspirants get stuck on complex 3-variable floor or flat puzzles, burning 8 to 10 precious minutes.
The Dual-Case Method for Puzzles
Never attempt to solve a seating arrangement or floor puzzle with a single mental model. The moment a clue offers two mutually exclusive possibilities (e.g., 'A sits second to the left of B, who faces either North or South'), immediately draw Case 1 and Case 2 side-by-side.
Read clues in sequence.
Fill direct information first.
Connect secondary clues without jumping between unrelated paragraphs.
One of the cases will inevitably contradict itself within 90 seconds, leaving the correct configuration crystal clear.
Data Interpretation: Approximation Shortcuts
In banking calculations, the options are rarely spaced within 0.1% of each other. Round numbers to nearest friendly values (e.g., convert 437 / 1892 into 440 / 1900). Learn fractional equivalents for 1/7 (14.28%), 1/9 (11.11%), 1/11 (9.09%), and 1/13 (7.69%).
