Answers
The cost of electricity would be RS 7410.
Given: Power = 1500W,100W
Time = 4h,5h
To find: Cost of electricity

Electricity is detailed as the transition of electric charge inside a instrument.
It is actually a sustainable strength beginning, therefore meaning that it has happened obtained through the renewal of basic energy beginnings to a degree coal, oil, oil, nuclear energy, as well as additional water.

As all these charges deliver the strength amount of the plant, therefore favorable circumstances cost is straightforwardly equivalent to the number of wholes create for one plant.
Lets calculate energy through formula,
Energy = power x Time taken
= 1500*4=6000= 6 units
=100*5=500 = 0.5units
Cost of electricity = 6*30 + .5*30
= 195 units
