Solve This!!
Solve the following numericals.
1. A vacuum cleaner is rated at 650 watt. How much electrical energy will it consume in 13 days if it is used for 1.5 hours daily?
2. Calculate the electricity bill of a house which has 5 bulbs of 60 watt each, 4 fans of 80 watt each, 2 tube lights of 9 watt each, one cooler of 140 watt and one geyser of 850 watt. These appliances are used for 5 hours daily and the bill is to be generated for the month of October. Take the cost of 1 unit of electricity as 2.40.

1)Answer is being cliped. Explanation:it is based on rating of the vacuum cleaner.
2)As a first step, write down the given data carefully. Then you could find the power consumed for 5 hours by each of the appliances and then take their sum to get the net power consumption per day. Then multiply this value by 31 days of October. After that find the equivalent electricity units and multiply this by Rs.2.40 to get the bill generated.
Formula used:
1 unit of electricity = 1000watt-hour
Complete step-by-step solution:
Let us first find the total energy consumed per day.
The 5 bulbs for 5 hours consume;
(5×60)watt×5h=1500watth
The 4 fans for 5hours consume;
(4×80)×5=1600watth
The 2 tube lights for 5 hours consume;
(2×9)watt×5h=90watth
(1×140)×5=700watth
One cooler for 5 hours,
(1×859)×5=4250watth
Now the total energy consumed by all these appliances would be their sum,
1500+1600+90+700+4250=8140watth
Now we know that 1 unit of current is equivalent to 1000watt-hour, so, the above total energy consumed would be equivalent to,
8140watth1000=8.140units
In the month of October we have 31 days, and the unit of electricity for that month would be,
8.140×31=252.34units
And we have the cost of 1 unit of electricity given as Rs. 2.40, so bill for the month of October would be,
252.34units×Rs.2.40=Rs.605.616
The bill generated for the month of October for the given power consumption is Rs. 605.616.
