Let's test some possible values of x and y...
Given: The ratio of x to y is \(\frac{7}{9}\)
Case i: It could be the case that \(x = 7\) and \(y = 9\)
When we increase both values by \(4\), we get: \(\frac{7+4}{9+4}=\frac{11}{13}\)
Case ii: It could also be the case that \(x = 14\) and \(y = 18\)
When we increase both values by \(4\), we get: \(\frac{14+4}{18+4}=\frac{18}{22}=\frac{9}{11}\)
Answer: E
