Question

Calculate the electricity bill amount of,if 4 bulbs of 40 for 5 hours and 4 tube lights of 60 watt for 5 hours and a tv of 100 watt for 6 hours and a washing machine of 400 watt for 3 hours if the cost of per unit is 3.60

Answer 1

Answer:

GIVEN:P1=4X40=160WATT=0.16kw

P2=4X60=240WATT=0.24kw

P3=100X6=600WATT=0.6kw

T1=5HR

T2=6HR

T3=3HR

ELECTRICITY=POWER X TIME

E=(P1+P2+P3)X(T1+T2+T3)

E=(o.16+0.24+0.6)x(5+6+3)

E=1X14=14kwh

E=14kwh

cost=rate x E

cost=3.60 x 14=Rs.50.4

electricity bill amount=Rs.50.4
