Answer 1

Answer:

here is ur answer

5 bulbs of 4ow each used for 5hr:

5*40w*5/1000

therefore 5*40w*5/1000=10001kwh

electric press for 4 hr and 500w:

5*40w*5/1000=2kwh

total energy for 30 days:1*30=30 units for bulbs

total energy for electric press for 30 days:

2*30=60 units

total energy=30+60=90units
