Answer 1

Answer:

HEY MATE HERE IS YOUR ANSWER

As we know Energy consumed = Power×time,

Energy consumed by lamps = 5×40 = 200W = 200×6= 1200W/hr

Energy consumed by fans = 4×80 = 320W = 320×10 = 3200 W/hr

Energy consumed by TV = 100W = 100×2 = 200W/hr

Energy consumed per day = 4600W/hr = 4.6KW/h

Energy consumed per month = 4.6×30 = 138KW/h

hence, cost = 138×6 = 826rupees.
