Logic
Who's Who?
Can you figure out who's who and who sits where?
Mr. Black is a butcher, and head of the shopkeepers'
club, which also includes a baker, a grocer, and
a candlestick maker. At their meetings, they all
sit at a square table. Mr. Black sits at the head
of the table, on Ms. Brown's left. Ms. White sits
on the grocer's right. Mr. Pink, who faces Ms.
Brown, is not the baker. What kind of shop does
Ms. White have? (Helpful hint: Draw a square or
rectangle to represent the table. Keep filling
in the information you learn and crossing out
whatever can't be true.)
Draw a square or rectangle to represent the table.
Write "Black/butcher" on the top side, since Black
sits at the head of the table.
You know that Brown is on the left side of the
table, and Pink is on the right, since you are
told that Black sits on Brown's left, and Pink
sits opposite Brown. That leaves the bottom side
of the table for White. Since White sits on the
grocer's right, Brown is the grocer. If Pink is
not the baker, White must be the baker. That means
Pink must be the candlestick maker.
