  21. Ole Santa's pack held 30 gifts
  22. All tagged for girls and boys.
  23. From the clues that you've been given,
  24. Now guess who made what toys.


Solution:

Each elf made at least three toys (line 4). One elf made three times as many as another (13-14), and three elves made consecutive amounts (5-8). If you eliminate duplicate amounts (3), two possible number combinations total 30: 12/6/5/4/3 or 9/7/6/5/3.

With either solution, Sue made the most (13-14). And we know that she made tops 17-18). She was not dressed in green (13-14), orange (15), red (5-6), or yellow (11-12), so she must be the elf in blue.

The two elves who made the least must be dressed in green (13-14) and red (5-6). Therefore the elf who made the least can not be Marcia (15). It also can not be Cher (5-8), or Jane (10), so Johnny must have made the least. And he made cars (9).

The elf who made the second most was not Jane (10)or Cher (5-8), so it must have been Marcia.And Marcia dressed in orange (15).

Since the two elves who made the least were in green and red, the elf in yellow must have made the third-smallest amount of toys. And that elf made trains (11-12).

Since the elf making sleds could not have made the second-smallest amount of toys (7-8), Marcia must have made the sleds. Cher is therefore the elf in yellow, and the person who made the second-smallest amount of toys is in red (5-8).

By elimination, Johnny is in green, and Jane is in red and made the balls. Since the elf in green made three toys, Sue must have made nine toys (13-14), and our amounts of toys must be: 9/7/6/5/3.

Sue (blue) made 9 tops.
Marcia (orange) made 7 sleds.
Cher (yellow) made 6 trains.
Jane (red) made 5 balls.
Johnny (green) made 3 cars.
