Hii
you are welcome
I = 10A
v =220v
p = vi
p = 10*220=2200
total number of hour =45*8=360
total cost =360*2200*6.70= ₹5306400

Answer:
Given
I = 10 A ; V = 220 V ;
We know that E = VIT
Energy = 220 X 10 X 8 X 45
= 792 X = 792 kwh
We know that 1 unit is 1 kwh
So total energy consumed in a month is 792 units.
Therefore Cost = 792 X 6.70
= ₹ 5306400 Ans.
