In a research experiment, Marie Curie is trying to invent a new compound that will have a 30% concentration of
nitrogen by mixing two mixtures of nitrogen, hydrogen, and oxygen in the ratio 5:3. The ratio of these gases in
the first mixture is 4:5:1 and in the second mixture is 5:7:3. Having found that the resultant concentration of
nitrogen in the mixture is not 30%, she dilutes it with more oxygen to make it 30%. Find the ratio of the original
mixture to the oxygen which was used for dilution.
