We carry different economic activities within our home too such as payment of electricity bill, water bill, telephone bill, etc. Currently, we can find such bills using the information and communication technology (ICT). For example, bill of public switched telephone network can be found by dialing1601.
Nepal Electricity Authority (NEA) charges the bill of electricity that public uses at their home. Bills are charged accordance to a capacity of meter used and a number of units consumes monthly. The NEA meters used in our home are from 220 volts to 400 volts.
Electricity charge as per the rule of electricity
authority:
Capacity of meter | Unit consumed | Amount |
5 Ampere | upto 20 | Rs 80 |
6 to 15 Ampere | upto 50 | Rs 365 |
16 to 30 Ampere | upto 100 | Rs 795 |
31 to 60 Ampere | upto 200 | Rs 1765 |
Energy cost as of 2071/72
Rs. 80 at the rate of Rs. 4 per unit up to 50 units
Rs. 7.30 per unit from 50 to 150 units
Rs. 9.50 per unit 150 to 250 units
Rs. 11.00 above 251
Some of the important information to the electricity consumer:
Water consumption is measured in terms of units. The unit of water consumed is measured by Flow meter. Nepal Water supply corporation (NWSC) sends the water bill every month. In Kathmandu Upatekya Khanepani Limited (KUKL) sends the water bill every month to its consumer.According to Nepal Water Supply Corporation, Tariff provided to all branch are as follow:
According to Nepal Water Supply Corporation, Tariff provided to all branch are as follow:
Pipe size (inch) | Minimum consumption (litre) | Minimum cost (Rs.) with meter | For more consumption cost per unit (Rs.) with meter | Main tap charge (Rs) without meter | Branch tap charge (Rs) without tap |
1/2" | 10 units | 110 | 25 | 560 | 200 |
3/4" | 27 units | 1490 | 40 | 3360 | 1600 |
1" | 56 units | 3420 | 40 | 9200 | 2700 |
1.5" | 155 units | 9600 | 40 | 20700 | 6500 |
2" | 320 units | 21600 | 40 | 42300 | 12000 |
3" | 881 units | 49500 | 40 | 131400 | 33000 |
4" | 1810 units | 97200 | 40 | 250200 | 62000 |
1 units mean 1000 litre of water consumption.
50% of water cost is charged a sewerage service charge.
The cost of telephone depends upon the number of calls that we make. Telephone company records the number of calls within their database system. Nepal Telecom Company (NTC) records the telephone bill and we should pay it monthly.
Telephone charge rate as per the rule of Nepal Telecom(NTC).
Rs.200 for a minimum of 175 calls Rs.1 per call above the minimum call.
Call charge = minimum call charge (C) + additional no. of calls (n) * addtional call rate (r)
i.e. call charge = C+n*r
Telecome service charge (TSC) = 10% of call charge
Value added tax (VAT) = (C + TSC)* 13%
Total amount = Call charge (C) + TSC + VAT
According to the certain rule imposed by government authority, the taxi fare is charged. The meters of taxi are provided and regulated by Department of Transport Management together with Nepal Bureau of Standard and Metrology (NBSM).
According to the current rule, the taxi users should pay the bill as mentioned below:
Time | Minimum fare | Rate per 200 m distance |
Morning 6:00 am to Evening 9:00 pm | Rs. 14 | Rs. 7.20 |
Evening 9:00 pm to Morning 6:00 am | Rs.21 | Rs. 10.80 |

Here, Consumed units of Baisakh=(1250-1050)=200 units
Consumed units of Baisakh=(1250-1050)=200 units
Minimum charge up to 20 units= Rs.80
Additional units =(200-20)=180 units
Charged of additional units =180× Rs.7.30 = Rs 1314
∴Total charge = Rs. 80 + Rs 1314
= Rs.1394 Ans
Here,
Consumption of electricity in Shrawan =2700-2500=200
Minimumcharge for first 50 units =Rs.299
Now, remaining units =200-50=150
Charges of remaining units =150×Rs.7.30 = RS 1095
∴Total charge =Rs. 299 + Rs 1095
= Rs. 1394. Ans.
Here,60 watt=\(\frac{60}{1000}\) kw=0.06 kw
7hrs.30 min = 7 hrs + \(\frac{30}{60}\)hrs
=7 \(\frac{1}{2}\)
=\(\frac{15}{2}\)hrs.
Hence, total consumed units in 7 hrs.30 mins =0.06 ×\(\frac{15}{2}\)= 0.45 units.
Now, charge for 0.45 units at the rate of Rs.7.30 per unit =0.45× 7.30=Rs 3.285
∴Total charge to be paid for using a bulb of 60 w of 7 hours 30 minutes =Rs 3.285 Ans.
Again,2000w=\(\frac{2000}{1000}\)=2 kw
2 hours 15 minutes =2 hrs +\(\frac{15}{60}\)hrs.=2 hrs + 0.25 hrs =2.25 hrs.
Total consumed units from 2000 of heater = 2.25× 2 =4.5 units.
Now, Daily charges for 4.5 units at the rate of Rs.7.30
=Rs.(4.5× 7.30)
= Rs.32.85
Now, Daily charge for 1 month = 32.85× 30=985.5.Ans.
Here, Consumption of electricity in Baisakh = 1250-1050=200 units
Charge for first 100 units =Rs.664
Remaining units=200-100=100
Charge for remaining units=100 × Rs. 7.35 =Rs.735
Total charge = Rs.664 + Rs.735 =Rs.1399
Now, remaining amount =Rs.1058 - Rs Rs.644=Rs.394
Here,for Rs. 7.35 = 1 unit can be consumed
for Rs.1 = \(\frac{1}{7.35}\) unit can be consumed.
for Rs.394=\(\frac{1}{7.35}\)×394 unit can be consumed.
=53.6 units can be consumed.
∴Total units that can be consumed for Rs.1058
= 100 + 53.6 = 153.6 Units Ans.
Here, Initial charge for meter taxi = Rs.7
Total fare = Rs.115
Taxi fare for distance travelled=Rs.115 -Rs.7 =Rs. 108
Again,per km fare= Rs.9
Hence, total distance travelled =\(\frac{Rs.108}{Rs.9}\)=12 km
Hence, a passenger can travel 12 km for Rs.115.Ans.
Here, Initial charge for meter taxi = Rs.7
Total fare = Rs.115
Taxi fare for distance travelled=Rs.115 -Rs.7 =Rs. 108
Again,per km fare= Rs.9
Hence, total distance travelled =\(\frac{Rs.108}{Rs.9}\)=12 km
Hence, a passenger can travel 12 km for Rs.115.Ans.
Here, N.C 6.34 = 10 Japanese Yen
N.C =\(\frac{10}{6.34}\) Ja panese Yen
∴N.C. 22484.81=\(\frac{10}{6.34}\)×22484.81=35465 Japanese Yen Ans.
Here, from the given table,
I.C. 100 = N.C. 160
or,I.C.1 = N.C. \(\frac{160}{100}\)
or, I.C 25=N.C.\(\frac{160}{100}\)×25= N.C.40
Again, $ 1= N.C.Rs 78
∴ $ 6.82=N.C 78 × 6.82 =N.C.531.96
£ 1 = N.C.121.41
£ 3.9 =N.C. 121.41× 3.9 = N.C. 473.499
Hence, average fare of these three countries in Nepali currency
\(\frac{40+531.96)+473.499}{3}\)
Rs.348.48 Ans.
Here, Air ticket from Ktm-London-Ktm=Rs 70225
Air ticket from London-Ktm-London =£ 604 =Rs. 604× 121.41
= Rs 73331.64
In Nepal, the air ticket is cheaper by
Rs. 7331.64 - Rs.70225 =Rs.3106
In percent, the ticket in Nepal is cheaper by
=\(\frac{3106}{70225}\)×100
=4.4229
=4.42% Ans.
Here, C.P $ 1= Rs.78, S.P =£ 1=Rs.121.41
Actual profit =S.P -C.P=Rs.(121.41-78)
= Rs.43.41
Percentage of profit= \(\frac{Actualprofit}{C.P}\) × 100%
=\(\frac{43.41}{78}\)× 100%
=55.65% Ans.
Here, using chain rule,
Japanese Yen 10 =N.C.6.28
N.C. 35800=Japanese Yen x(say)
Here,10× 35800 = 6.28× x
∴ x=\(\frac{10× 35800}{6.28}\)
= 57006.37
Hence, N.C. 35800=Japanese Yen 57006.37 Ans.
Here, Let,£
Let,£ x can be exchange for Rs. 31200
∴£x=Rs.31200.
Rs.390 = $ 5
$20=£15
Now, using chain rule,
x× 390× 20 =31200× 5× 15
∴ x= \(\frac{31200×5×15}{390× 20}\)
= 300
Hence, number of pounds that can be exchanged forRs.31200 is£300.Ans.
Here,
Let, $ 55 =£x
Then,£x=$55
$1 =Rs.78
Rs.117 =£1
Now, x×1×117 =55× 78× 1
∴x=\(\frac{55×78×1}{1×117}\)
=36.67
∴$55=£36.67 Ans.
Here, Rs. 78.59 = $1
or,Rs,1=$\(\frac{1}{78.59}\)
or, Rs. 70250 =$\(\frac{1}{78.59}\)×70250
= $ 893.88 Ans.
