Answer:

Yes! Here is your answer!

Explanation:

Energy = Power*time

Energy consumed by 100 W bulb per day = 2∗100 Wh              

                                                                     = 0.2 kWh

Energy consumed by 40 W bulbs per day = 4∗40∗4 Wh

                                                                     = 0.64 kWh

Total energy consumed per day = 0.2 + 0.64 kWh

                                                  = 0.84 kWh

Therefore, the energy consumed in 30 days = 30∗0.84 kWh

                                                                                   = 25.2 kWh
