Answer:

The Electric Bill at the end of a month will be Rs. 5400.

Explanation:

Electric Geyser = 1000W

Time = 30 mins or, 0.5 hr

No. of units = (Wattage*hours)/100

= (1000*0.5)/100 kWh

= 5 kWh

No. of units in a month = 5*30 kWh

= 150 kWh

Microwave Oven = 2000W

Time = 2 hrs

No. of units = (Wattage*hours)/100

= (2000*2)/100 kWh

= 40 kWh

No. of units in a month = 40*30 kWh

= 1200 kWh

Total units = (1200+150) kWh

= 1350 kWh

Cost of 1 unit = Rs. 4

Cost of 1350 units = Rs. (1350*4)

= Rs. 5400

Hope this helps.
