No. of bulbs=5
Power= 25 W
Energy consumed in 1 day= Power×Time= 25×6= 150Wh
Energy consumed in 30 days= 150×30 Wh= 4500Wh= 4.5 kWh
No. of fans= 2
Power= 70W
Energy consumed in 1 day= 70×10= 700 W
Energy consumed in 30 days= 700×30 Wh= 21000 Wh= 21 kWh
Total energy consumed= 21+4.5 kWh= 25.5 kWh= 25.5 units
Total expenditure= 25.5×2= 51 rupees
Power= 25 W
