From a standard pack of cards, I remove four cards, one of each suit, and one of each of he ranks Jack, Queen, King and Ace. I lay them out in a line face downwards. Now, you have been given the following facts:
(a) The Heart isn’t next to the Club.
(b) No card is next to its immediate senior in rank.
(c) The colors of the suits alternate.
(d) The king and Queen are facing opposite directions.
Identify the four cards and their correct order.
I go for:
King Hearts - Jack Spades - Ace Diamonds - Queen Clubs (or the reverse).
(a) and (c) dictate the suits: H - S - D - C, or the reverse.
(b) dictates the ranks: Q - A - J - K or the reverse.
Now we're left with Q-H and K-C or Q-C and K-H. In a standard deck, both kings and the queen of hearts face their left, but the queen of clubs faces her right. So only K-H Q-C satisfies (d).
