Explanation:
1 unit = 1KWH
a. energy consumption = power x time
= 1000 x 2 = 2000 WH. = 2KWH ( 1 day)
in one month, 30 days
energy consumption = 2 x 30 = 60KWH
cost = 5 x 60 = 300 rupees
b. energy consumption = 10 x 60 x 5 = 3000
= 3KWH ( 1day)
in month, it is 30 x 3 = 90KWH
cost = 5 x 90 = 450 rupees.
