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 ?
-
- Rs. 16.00 gain
- Rs. 16.00 loss
- Rs. 20.00 gain
- None of these
Correct Option: D
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
