Tritium (halflife= 12.3 y) is used to verify the age of expensive brandies. If an old brandy contains only 1/16 of the tritium present in new brandy, how long ago was it produced?

in 12.3 years, new brandy contains 1/2 of the original tritium.
in 24.6 years, new brandy contains 1/4 of the original tritium.
in 36.9 years, new brandy contains 1/8 of the tritium.
In how many years will it contain 1/16 of the original tritium?
