Please scroll down to see the correct answer and solution guide.
Right Answer is:
SOLUTION
Energy consumed is given by the relation, E = P x T
Energy consumed by the 100 watt bulb in 30 days is given by,
Similarly energy consumed by four 40 watt bulbs,
Hence, total energy consumed = 6 kWh + 19.2 kWh = 25.2 kWh.
