Let \(x\) be number of 5$ bills and \(y\) be number of 10$ bills, so question is find \(\frac{x}{y}\).

1) \(\frac{(x+y)}{(5x + 10y)} = \frac{1}{9}\)
and this gives \(\frac{x}{y} = \frac{1}{4}\)

sufficient , Select A or D

2) \(5x + 10y = 360\)
=> \(x + 2y = 72\)
multiple solutions for this equation.
Not Sufficient.

Hence Answer is A
