Pure milk costs Rs. 16 per litre. After adding water the milkman sells the mixture Rs. 15 per litre and thereby makes a profit of 25%. In what respective ratio does he mix milk with water?
Solution
Selling price is Rs 15 and Profit is 25%
=> Cost Price = $\frac{15}{1.25}$ = Rs 12
=> In every litre of solution, there is Rs 12 worth milk.
But the actual cost of milk is Rs 16.
=> Ratio = 12 : 4 = 3 : 1
