Solution:Total battery capacity of earphone A = 32% of 1500
= 480 mAh
Charged battery capacity of earphone A = 320 mAh
Battery capacity of earphone A yet to be charged
= 480 - 320 = 160 mAh
Similarly, we can calculate for other earphones as well:
Earphones | Total battery capacity (mAh) | Charged battery capacity (mAh) | Yet to be charged battery capacity (mAh) |
P | 480 | 320 | 160 |
Q | 270 | 240 | 30 |
R | 150 | 100 | 50 |
S | 240 | 210 | 30 |
T | 360 | 300 | 60 |
Time taken to charge 210 mAh of battery of earphone S = 35 min
Time taken to charge 240 mAh of battery of earphone S = (35/210) × 240 = 40 min
