AI explanation

The selling price of Rs. 11 represents a 25 percent profit, so the cost price is 11 divided by 1.25, which equals Rs. 8.80 per kg. Using the rule of alligation with the non-ration price of Rs. 10 and ration price of Rs. 8 against the mean price of 8.80, we get (8.80 minus 8) to (10 minus 8.80). The ratio is 0.80 to 1.20, which simplifies to 2 to 3.
