Answer:

2160 rupee.

Explanation:

an electric heater of power 2000 watt

an electric iron of power 1000 watt

so total wattage =(2000+1000)=3000 watt.

if that used daily 4 hours..then it consumed (3000×4)

=12000 watt.

=12 b.o.t

=12 unit.

in a month power will consume =(12×30)

=360 unit.

if every unit cost 6 rupees...

then total cost in a month = (360×6) =2160 rupees.
