Answer:
Rs 450.00
Explanation:
Total energy consumption per day = 1000J × 5 × 3600=18000 kJ
Energy per each unit = 1kWh = 1000 × 3600 = 3600 kJ
No.of units consumed per day = 18000/3600 = 5 units
No.of units consumed for 30 days = 5 × 30 = 150 units
therefore, cost of energy per 30 days = 150 units × Rs 3.00 = Rs 450.00
