Classical Collection - Logic Puzzles
In my collection of classical music, I have a range of pieces that last 6, 7, 8 and 9 minutes.
The piece by Bach lasts 8 minutes, and the CD lasts longer than the piece by Holst.
The piece on DAT tape is longer than the piece by Beethoven.
The single lasts 7 minutes, and the album does not contain any Holst.
The piece by Butler is on the DAT tape.
Can you determine which piece of music is in which format, and how long each lasts?
