Rishi bought 30 kg of sugar at the rate of Rs. 9 per kg and 45 kg of sugar at the rate of Rs. 10 per kg. He mixed both type of sugar and sold the mixture at the rate of Rs. 9.75 per kg. What was his gain or loss in the selling of whole sugar?
Correct Answer: Rs. 11.25
Explanation:
Total quantity of sugar = 45 + 30 = 75
Gain or loss can be calculated as
9.75 x 75 - (30 x 9 + 45 x 10)
= 731.25 - 720
= 11.25
Hence, in the overall transaction, Rishi got Rs. 11.25 gain.
