(D) The formula for energy consumed in kilowatt-hour $(kWh)$ is given by: $E = \frac{P 	imes t}{1000}$,where $P$ is power in watts and $t$ is time in hours.Given:Number of bulbs = $10$Power of each bulb = $50\,W$Total power $(P)$ = $10 	imes 50\,W = 500\,W$Time per day = $10\,h$Number of days = $30$Total time $(t)$ = $10 	imes 30 = 300\,h$Energy consumed $(E)$ = $\frac{500\,W 	imes 300\,h}{1000} = \frac{150000}{1000} = 150\,kWh$.Therefore,the total energy consumed is $150\,kWh$.

How much energy in kilowatt-hour $(kWh)$ is consumed in operating ten $50\,W$ bulbs for $10$ hours per day in a month ($30$ days)?
