Expert Answer:

Since power of heater is given and it is connected to supply of 220V, so current through it is 2000/220 = 100/11A

The remaining current that can flow is 15A - 100/11 = 65/11A

This current has to flow through x bulbs.

Current through 1 bulb = 100/220

So total current through x bulbs = 65/11

65/11 = x ( 100/220)

Find x
