Answer / gopalakrishnan

50 minutes

for example let us take four fans at 100% load for 20 minutes.
100% load means 4 fans = 20 minutes
75% load means 3 fans = 30 minutes
50% load means 2 fans = 40 minutes
25% load means 1 fan = 50 minutes

Answer / prakash kusuma

at 25% load a 6kva UPS give back up of 50 min
as at 100% = 20 min ok
50% = 40 min
25% = 50 min (40 min + 20 min = 60 min(no load)
- 10 min(25 % load )= 50 min( back up)
