A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y. 
Product X is produced by mixing chemical A and chemical B in the ratio of 5 : 4. Chemical A is prepared by mixing two raw materials, P and Q, in the ratio of 1 : 3. Chemical B is prepared by mixing raw materials, Q and R, in the ratio of 2 : 1. Then the final mixture is prepared by mixing 8640 units of product X with water. If the concentration of the raw material Q in the final mixture is 50%, how much water had been added to product X?
