A 100 \(watt\) electric bulb is used for 5 \(hours\) daily and four 60 \(watt\) bulbs are used for 5 \(hours\) daily. Calculate the energy consumed in the units of \(kWh\) in the month of January.
 
[Note: Enter the answer up to two decimal places by rounding off the third decimal value].
 
The formula for electrical energy is
 
i=i×i
 
Energy used by 100 \(watt\) bulb is  \(Wh\).
 
Energy used by four 60 \(watt\) bulb is  \(Wh\).
 
Hence, the total energy used per day,
 
=i+i=iWh

On converting \(Wh\) to \(kWh\), we get  \(kWh\).
 
Number of days in January \(=\) 31 days
 
Energy used in January =i×i
 
Thus, the energy consumed by the bulbs in the month of January is  \(kWh\).
