Exam Hall Pitfalls & Elimination Tactics: Arithmetic

  • 1Reversing percentage bases: A 25% increase followed by a 20% decrease returns to 100%, not a net 5% gain.
  • 2Average Speed Trap: Average speed is never the arithmetic mean (S1 + S2)/2; it is Total Distance / Total Time = 2*S1*S2 / (S1 + S2) for equal distances.
  • 3Units mismatch: Mixing km/h with m/s without converting (multiply by 5/18 or 18/5).
