Reasoning and Quantitative Aptitude
Divisibility by 11 — Alternate digit sum difference: 7249 → (7+4) - (2+9) = 0, divisible. Quick mental check for large numbers.
Direction Sense — Clockwise: "NEWS" (N→E→S→W). Right turn = clockwise; Left = anti-clockwise. 180° = opposite direction.
Blood Relations Key — Mother's brother = Maternal uncle; Father's brother = Paternal uncle. Daughter's husband = Son-in-law; Son's wife = Daughter-in-law.
Calendar: Odd Days — Ordinary year = 1 odd day; Leap year = 2 odd days. Century: 400-divisible = 0 odd days; else 100-years have pattern (1,1,0 for 300 years).
Time and Work Formula — If A does work in 'a' days, B in 'b' days, together = (a×b)/(a+b) days. Reciprocal addition: 1/a + 1/b = 1/combined.
Percentage-Fraction Conversion — 50%=½, 33⅓%=⅓, 25%=¼, 20%=⅕, 12½%=⅛, 16⅔%=⅙, 10%=1/10. Instant calculation in exams.

Simple Interest Trick — SI = (P×R×T)/100. If SI doubles in time T, rate R = 100/T. E.g., doubles in 10 years → R = 10%.
Average Addition — Adding one number: New avg = Old avg + (New number - Old avg)/(n+1). Subtracting: reverse. Saves recalculation time.
