Alok bought 25 kg of rice at the rate of Rs. 6.00 per kg and 35 kg of rice at the rate of Rs. 7.00 per kg. He mixed the two and sold the mixture at the rate of Rs. 6.75 per kg . What was his gain or loss in this transaction?
Correct Answer: None of these
Explanation:
C.P. of 60 kg mix = Rs. (25 x 6 + 35 x 7) = Rs. 395
S.P. of 60 kg mix = Rs. (60 x 6.75) = Rs. 405
Gain = Rs. (405 - 395) = Rs. 10
