Answer 2

Answer:

The cost of consumed electrical energy is 150 rupees.

Explanation:

It is given that in a house of 5 bulbs rating is 200V-100W.

Bulbs are switched on for 5 hours per day. And cost of one unit is 2 rupees. It is asked to find the cost of energy consumed in 30 days.

To find the number of units we multiply Power in kilowatt with time in hours.

Power in kilowatt is $\frac{100}{1000} =0.1$

Total time will be $5*5*30=750$

Number of units $=0.1*750=75$

Cost of electrical energy $=75*2=150$

The cost of consumed energy is 150 rupees.
