Answer 2

Rana was away for 14 hrs (7pm to 9am next day ).

Now If you use 1000 watts of power for 1 hr then you use 1 unit.

So According to it..

100 watt bulb will consume

100 x 14 = 1400 / 1000 = 1.4 unit

2, 60 watt bulbs will consume

2 x 60 x 14 = 1680 / 1000 = 1.68 unit

80 watt fan will consume

80 x 14 = 1120/1000 = 1.12 unit

Total of

1.4 + 1.68 + 1.12 = 4.2 units he wasted

According to Question 1 Unit Electricity Cost is ₹ 12

So Total of  ₹ 50.4 Penalty he will have to pay.
