Lesson 2.4: Average & Alligation

Description:
Average is used for speed and marks-based problems, while alligation is useful for mixtures.

Key Topics:

  • Weighted Average: Marks and salary problems.

  • Alligation Rule: Mixing two different values to get a mean value.

Example:
Average of 10, 20, 30 = (10+20+30)/3 = 60/3 = 20.
