calculate the cost of watching two movies on colour T.V for the month of september . ( data : watt of tv = 60 , duration of on movie = 2 hours 30 mins , cost/unit os rs 4 )

Its is a 60 W TV. The movie ran for 2.5 hours.
Two movies = 5 hours.
1 unit = 1 KWh
So, 60/1000 = 0.06 units
Kilowatts * hours = 0.06 * 5 = 0.3 KWh
Cost of 1 unit = 4 /unit
Cost of 0.3 units = 0.3 * 4 = 1.2 rupees.
