You have ten cards numbered 1(ace), 2, 3, 4, 5, 6, 7, 8, 9, and 10. Your
task is to arrange them in a particular order and put them in a
stack, hold the stack in your hand, and then do the following:
Put
the top card on the table faceup. Put the next card on the bottom of
the stack in your hand. Put the next card on the table. Put the
next card on the bottom of the stack, and so on, continuing to
alternate cards that go on the table and under the stack, until all
ten cards are on the table.
The
trick: To lay the cards on the table in
numerical order. The first card you put on the table will be number
1(ace), the next card you put on the table will be number 2, the next
card you put on the table will be number 3, and so on, until the last
card placed on the table will be number 10.
In what
order should the cards be arranged in the original stack so that this
will happen?
Here is an interesting variant:
Start with all the cards in one suit in the deck: ace, 2, 3, 4, 5, 6, 7, 8,
9, 10, jack, queen, and king. Arrange the cards in a particular
order in your hand. Then spell the name of each card, putting one
card on the bottom of the stack for each letter in the name of the
card. For ace, you would say "ACE ace," putting three cards on
the bottom of the stack and laying the fourth card faceup on the
table (this card will be the ace). Then continue by saying "TWO
two," putting three cards on the bottom of the stack and laying the
fourth card (a 2) on the table just as you say "two." Continue
in this way all the way through jack, queen, and king, each time
ending the spelling by saying the card you just spelled as you lay it
faceup on the table.
What
order do the cards have to be in originally for this to work out?
