We know , power = energy / time =>energy = power × time
two bulbs = 100×2=200W per day
two coolers = 250×2=500W per day
They work 6 hour per day. So the energy consumed in 1 day :-
Bulbs = > 200×6=1200W/h=> 1.2KW/h
Coolers=>500×5=2500W/h=>2.5KW/h
Total energy consumed = 3.7KW/h
1 unit = 1KW/h
1unit cost 1.75
3.7unit =?
=>3.7×1.75=6.475rupees will ne the monthly bill
