Question

please answer it if you love maths Q. there is a home in which 10 bulbs of 12w and 5 fans of 15 w is used now calculate the electricity bill for February 2020 (note-bulbs are used 10 hours per day)​

Answer 1

Consumed electric energy =power ×No of appliances ×time ÷1000

electric energy Consumed by bulb

(12×10×10)÷1000=1.2kWh

rs=1.2×6=7.2

The total bill for 29 day= 7.2×29=208.8

electric energy Consumed by fan

(15×15×1)÷1000=0.075

rs=0.075×6=0.45

The total bill for 29 day=0.45×29=13.05

The total bill for month=208.8+13.05=221.85rs
