GIVEN;

Electric motor = 1kw is used for 3 hours .....

Electric bulb = 2 × 6w is used for 8 hours.....

Changing electric bulb = watt to kilowatt

(1kw=1000w)

2×6/1000=0.012kw

Electric motor = 1kw × 3hrs = 3kwh....

Electric bulb = 0.012kw × 8hrs= 0.096kwh

total energy = motor energy + bulb energy

= 3kwh + 0.096kwh

= 3.096kwh

daily consumption = 3.096 × 5 = Rs 15.48

monthly consumption = 15 .48 ×30 =Rs. 464.4

cost of energy used in the month of November is 464 rupees...........

hope it helps you ☺️
