A house hold usesan electric geyser of 1000w for 30 minutes a day.

A micro wave oven of 2000w for 2 hours a day.

Electricity bill at rs 4 per unit.

To find:

What will be the electricity bill for one month.

Explanation:

Consider there is a 30 days in a month.

Electric geyser of 1000w for 30 minutes a day.

Total electricity utilized by geyser per month = 1000 × $\frac{1}{2}$ ×30 = 15 kw.Hr.

Total electricity utilized by micro wave oven per month =  2000 × 2× 30

                                                                                            = 120 kw.Hr.

So total electricity used =  120 +15 = 135 kw.Hr.

That is 135 unit.

For one unit rate = 4 Rs.

For 135 unit rate = 4×135 = 540 Rs.
