medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate capacity loss
20% of 3000 mAh = 0.20 * 3000 = 600 mAh lost.Step 2: Subtract loss from initial capacity
3000 mAh - 600 mAh = 2400 mAh remaining.Final Answer:
2400 mAh -> Option AQuick Check:
Remaining capacity = 3000 - 600 = 2400 mAh [OK]
Quick Trick: Subtract percentage loss from initial capacity [OK]
Common Mistakes:
- Adding instead of subtracting loss
- Calculating wrong percentage
- Mixing up initial and final values
