2.Calculate the electricity bill amount for a month of June, if 6 bulbs of 100W for 5 hours, 4 tube lights of 60 W for 5 hours, a TV of 50 W for 6 hours are used per day. The cost per unit is ₹ 5.
Answers
675₹
we know, days in june =30 days
energy used by bulbs in 1 day (100×5×6)
= 3000 w/h = 3 kw/h
energy used by tube lights in 1 day (60×4×5)=1200w/h= 1.2 kw/h
energy used by tv in 1 day (50×1×6)=300w/h=.3kw/h
total energy used in 1 day (3+1.2+.3) kw/h = 4.5 kw/h
total energy used in 30 days (4.5×30) = 135 kw/h
The cost per unit is ₹ 5
The cost in 135 unit is (135×5) ₹ = 675 ₹
Answer:
Total Bill Amount = ₹180.40
Explanation:
From the above question,
They have given :
Electricity bill calculation is done by multiplying the number of kilowatt-hours (kWh) used by the cost per kWh. The cost per kWh is determined by the electricity company and is usually found on the monthly bill. The total wattage used, the total hours of usage, and the cost per unit are used to calculate the total electricity bill.
The total wattage is calculated by multiplying the wattage of each appliance by the number of hours used.
The total kilowatt-hours used is determined by dividing the total wattage by 1000.
Finally, the total bill amount is calculated by multiplying the total kilowatt-hours used by the cost per unit.
Total Wattage = (6 x 100) + (4 x 60) + (50)
= 780 W
Total Hours of Usage = (5 x 6) + (5 x 4) + (6)
= 46 hours
Total Units Consumed = (780 x 46) / 1000
= 36.08 units
Total Bill Amount = 36.08 x 5
= ₹180.40
