Latha went to the market to buy some vegetables. While leaving her house she checked her wallet and found out that she had some hundred-rupee notes and some twenty-rupee notes. After shopping she had the same number of hundred- rupee notes as she originally had twenty-rupee notes and the same number of twenty-rupee notes as she originally had hundred-rupee notes. If the remaining money was one-third of what she initially had while stepping out of her house, find the initial ratio of the number of hundred-rupee notes and twenty-rupee notes.
