medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Understand weighted average formula
Weighted average = (value1 x weight1) + (value2 x weight2)Step 2: Calculate weighted average
(30 x 0.7) + (20 x 0.3) = 21 + 6 = 27Step 3: Re-check calculation
Recalculate carefully: 30x0.7=21, 20x0.3=6, sum=27Final Answer:
27 -> Option BQuick Check:
Weighted average = 27 [OK]
Quick Trick: Multiply values by weights, then add [OK]
Common Mistakes:
- Ignoring weights
- Adding weights instead of multiplying
- Mixing up values and weights
