~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


If Bill has 2 times as many quarters as dimes, then he can combine every two quarters with one dime. 
The value of each such group will be 2*25 + 10 = 60 cents, and the number of all such groups would be {{{480/60}}} = 8.

<U>Answer</U>. 16 quarters and 8 dimes.
