medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Determine charging rate per percent
20 minutes / 80% = 0.25 minutes per 1%Step 2: Calculate time for 100%
0.25 x 100 = 25 minutesFinal Answer:
25 minutes -> Option AQuick Check:
Charging time = 25 minutes [OK]
Quick Trick: Use unit rate to find total time [OK]
