Question

15 bulbs of 40 watt are used for 6 hours a day along with one 100 watt bulb for 2 hours. what is the bill amount if the cost of a unit is Rs3​

Answer 1

Answer:

11400

Explanation:

15 X 40 X 6 = 3,600

1 X 100 X 2 = 200

Total Watts Used = 3600 + 200 = 3800 units consumed

1 Unit = 3 Rs

3800 Units = 3800 X 3 = 11400
