Question: what is the difference between 5star and 3 star refrigerator?
Answer: Which means a 3 star rated refrigerator will consume about 100-150 units more than a 4 star and similarly a 4 star rated refrigerator will consume 100-150 units more than a 5 star per year. It we take average tariff of Rs 5 per unit then it converts to Rs 500 – Rs 750 difference in operational cost.
