Quantitative Aptitude – Races & Games of Skill
1. Basic Concepts
- Use relative speed when two players or objects are racing: same direction → subtract speeds; opposite → add.
- Head start is considered as distance or time. Time = distance / relative speed.
2. Time and Distance in Races
- If A beats B by d meters, then when A finishes, B covers (total − d) meters.
- Ratio of speeds = Distance covered by A : Distance covered by B in same time.
3. Quick Tips
- Draw simple diagrams to visualize race layout.
- Use consistent units throughout.
4. Mistakes to Avoid
- Misjudging start point or race type (same start, different paths).
- Ignoring whether time or distance is being compared.
5. Revision Checklist
- Practice race problems involving head-start, finish difference, and relative time.
Summary: Know how to use relative speed, head-start conversions, and time/distance ratio to solve race and competition problems efficiently.
