Question

calculate electric energy consumed when 3 bulbs of 100 W, 2 fans of 60 W and television of 100 W is used 6 hours daily in a month of 30 days. if electric energy cost rs. 3 per unit, calculate complete expenditure for that month

Answer 1

total power= 300+120+100→520 W
energy consumed for 1 day=520 x 6. →3120
for 30 days energy= 93600
total cost= 93600 x 3 → 280800
ppz mark it as brianliest answer

Answer 2

total power =(3×100+2×60+100)W=520W
title time =30×6=180hrs
Power=Enegy/Time ----(1)
we have P=520W
T=180hrs
we can find energy from eqn 1
520=energy/180
energy=520×180=93600
cost of per unit =₹3
cost of 93600 unit= 3×93600=₹280800
