Answer:
12/5 bottles
Explanation:
Since 5/4 of a tone when melted can collect 12/5 bottles as given in the question, unless the question was to have a different figure at the end otherwise the question is like a repetition of what is in the question. Therefore, for 5/4 tone melted as given, it is only possible to collect 12/5 bottles. In case the figure was to be 4/5 tone then then the bottles is found by cross multiplication as follows
If 5/4 t=12/5
4/5 t= x
X=(4/5*12/5)/5/4=1 67/125
Please note that since this is not what was asked, I've put it here just in case there was typo in the last part of the question.
