Solve the given problem:
An electric refrigerator rated 200 \(watt\) operates 8 \(hours/day\). What is the cost of the energy to operate it for \(30\) days at \(Rs\ 3.00\ per\ kW h\)?
The formula for electrical energy is
The total energy consumed by the refrigerator in \(30\) days would be \(Wh\).
In terms of \(kWh\), it is written as \(kWh\).
Thus, the cost of energy to operate the refrigerator for \(30\) days is
