The total number of hours=2*30=60
Total energy consumption=60*1,1= 66 kWh
Energy cost = 66*5= Rs 330
It is to be noted that the iron has a thermostat, which trips when the set temperature is reached. The thermostat also resets when the temperature falls. This results in a duty cycle with an “on” period followed by an “off” period. This would result in a substantially lower energy consumption.

electric iron is using 1100w in 1 hour then it consumes 2200w in a day n the month of april is of 30 days so,
electicity consumed in 30 days= 2200×30=66000w=66kwh or 66unit
and the rate is 5 rupees per unit so
cost of 330 units will be=66×5=rs. 330 ans.
