A car increases its speed by 25%, then decreases it by 25%. The final speed compared to original is:
ASame
BHigher
CLower (by about 6%)
DTwice
Answer & Solution
Correct answer: C. Lower (by about 6%)
Start at 100. +25% → 125. -25% of 125 → 125 × 0.75 = 93.75. So final ≈ 93.75 — about 6.25% lower than original. Percentage changes don't 'cancel' because the base changes.
