Every thing is good, but I can't understand how to calculate the mean price. In this problem, cost of the mixture is obtained by multiplying it with hundred $(10 \times 100).$

Shouldn't it be the ratio of rice at Rs 10.80 per Kg to rice at Rs 9.30 per Kg instead of rice at Rs 9.30 per to rice at Rs 10.80 per Kg as mentioned in the question.

My query might seem confusing, I just want to ask if ratio to be found is correct or should we find the reverse ratio?
