Answer:

plz follow me on and mark as brainalist plz

Step-by-step 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
