Answer 1

Answer:

72 rupees is your answer

Answer 2

Given:

Rate of electricity = Rs-3.00 per unit

Power rating of Fan = 80 watt

To Find:

Monthly cost of running fan 10 hours daily.

Calculation:

- The fan runs daily for 10 hours

⇒ Daily power consumption = Power Rating × time

⇒ Daily power consumption = 80 × 10 = 800 W

- Monthly power consumption = 800 × 30

⇒ Monthly power consumption = 24,000 W = 24 KW

- Monthly cost = power consumption × rate of electricity

⇒ Monthly cost = 24 × 3

⇒ Monthly cost = Rs. 72

- Hence, the monthly cost of running an 80 W fan for 10 hours daily is Rs. 72
