Hey mate,.
Since the arrangement is in parallel :
Voltage across the bulbs is same.
The summary of the current in each path is equal to the current supplied.
The total current in this case is 100Ampheres
Total voltage = 220 V
We can get the power supplied :
P = VI
100 × 220 = 22000 W
The bulbs are rated at 75 W per bulb.
Total bulbs :
22000 / 75 = 293.3
Therefore 293 bulbs can be blow.
Hope it will help you
