Three galsses are filled with a mixture of milk and water in the ratio 4 : 3, 5 : 4 and 7 : 6 resectively. If the contents of three glasses are poured into a single vessel. then the ratio of water to milk in the new vessel is:
1
\((\frac{4}{7}+\frac{5}{9}+\frac{7}{13}) : (\frac{3}{7}+\frac{4}{9}+\frac{6}{13})\)
2
\((\frac{4}{3}+\frac{5}{4}+\frac{7}{6}) : (\frac{3}{4}+\frac{4}{5}+\frac{6}{7})\)
3
(1 + 1 + 1) : \((\frac{4}{3}+\frac{5}{4}+\frac{7}{6})\)
4
\((\frac{3}{7}+\frac{4}{9}+\frac{6}{13}) : (\frac{4}{7}+\frac{5}{9}+\frac{7}{13})\)
