Final answer:
The electric energy consumed in 30 days is calculated by finding the energy consumed by each type of bulb and adding them together.
Explanation:
To calculate the electric energy consumed in 30 days, we need to determine the total energy consumed by each type of bulb and add them together.
For the two 60 W bulbs lit for 4 hours, the total energy consumed per day is 2 * 60 W * 4 hours = 480 Wh = 0.48 kWh.
For the three 100 W bulbs lit for 5 hours, the total energy consumed per day is 3 * 100 W * 5 hours = 1500 Wh = 1.5 kWh.
Adding the energy consumed by the two types of bulbs gives us a daily consumption of 0.48 kWh + 1.5 kWh = 1.98 kWh.
Therefore, the electric energy consumed in 30 days is 30 days * 1.98 kWh/day = 59.4 kWh.
So, the correct option is (c) 330 kWh.
