The cost at 5 paise/KWH of operating an electric motor for 8 hours which takes 15 amp at `110V` is

A

Rs. 66

B

66 paise

C

37 paise

D

Rs. 6.60

Text Solution

Verified by Experts

The correct Answer is:
B
Cost `=(5 paise)/(KWH) xx hour xx 15 amp xx 110`
`= (5)/(10^(3) xx wH) 8 xx 15 xx 110 = (66000)/(10^(3)) = 66` paise
