Energy by bulbs in a day = 4*50*6
= 1200W/1000 = 1.2kwh
energy by tube lights in a day = 3*40*8
= 960W/1000 = 0.96kwh
energy by a tv in a day =100*6
= 600W/1000 = 0.6kwh
energy by refrigerator = 300*24
=7200W/1000 = 7.2kwh
Total energy =1.2+0.96+0.6+7.2=9.96kwh
cost in 30 days =9.96*30 = 298.8kwh
Total cost = 298.8 * 2.5 = 747 rupees
hope it helps u
