Ans. Power of 4 bulbs of 100 Watt = {tex}4\times 100 = 400W = 0.4KW{/tex}
Power of 5 Fans of 110 Watt = {tex}5\times 110 = 550W = 0.55KW{/tex}
Total Power = 0.4 + 0.55 = 0.95KW
Time = 12hours
Electricity Consumed = {tex}Power \times time{/tex}
=> {tex}0.95\times 12 = 11.40 \space KWh{/tex}
Rate of Unit = 2.50 Rs.
Total Expenditure = {tex}11.40 \times 2.50 = 28.50 Rs{/tex}
