Answer» FAN= 12 kWhTv= 7.2 kWhAltogether = 19.2 kWhExplanation:GIVEN:-Fan. Power= 50W= 0.05kW TIME= 8 hoursTV. Power= 40W= 0.04kW Time= 6 hoursEnergy consumed by fan in a day= Power*time= 0.05*8= 0.4 kWhEnergy consumed by fan in 30 days= 0.4*30 = 12kWhEnergy consumed by TV in a day= Power*time= 0.04*6= 0.24 kWhEnergy consumed by TV in 30 days= 0.24*30 = 7.2kWhTherefore the energy consumed by fan and Tv TOGETHER in a month of 30 days is 7.2+12= 19.2 kWh.
