Answer:
power given = 900 watt
voltage = 220 volts
total time for which the AC is operated = 3 hours in 7 days total number of hours = 21 hours
rate per kWh = Rs 4 / kWh
the total power consumed = 2700 watts in a day
total power consumed in 7 days = 2700 * 7 watts
= 18900 watts
total power costs = (18900/1000) * 4 = Rs 75.6
