Question

calculate the cost of operating a 150w fan for the month​

Answer 1

Answer:

1000w= 1kw

then, 150w= 0.15 kw

and if you use the fan for 24 hour

then,0.15 kw × 24 hour= 3.6 kwh

and 1kwh= 1 unit

therefore if the fan takes 3.6 unit

then it would take 3.6 unit×30 days =108 unit for a month

and according to rate of unit in city

1unit rates 7or 8 rs

then for 30 days it would be

108unit × rs 8= rs 864

the answer can be different according to rate of unit in village and city
