Thank goodness the Glorious Ice Cream Parlor serves its sundae
sauce and ice cream in two separate dishes! The new waitress put
every item ordered by a party of four in front of the wrong person.
She served Jenny chocolate ice cream and fudge sauce; Ruth
got mint ice cream and marshmallow sauce; Dave was served
coffee ice cream and butterscotch sauce; and Martin got
vanilla ice cream and chocolate sauce.
Although nobody got either item he or she had ordered,
nobody got both the items ordered by anyone else.
After a brisk shuffle, when everything was where it belonged,
the person sitting opposite Martin had the fudge sauce, the one on
Dave's left had the chocolate ice cream, Ruth's right-hand
neighbor had the coffee ice cream, and Jenny was sitting between the
person who ordered butterscotch sauce, on her right, and the one
who ordered vanilla ice cream, on her left.
What had each person originally ordered?
Answer
Sitting clockwise around the table are Jenny, Ruth, Dave, and Martin.
Jenny ordered coffee ice cream with marshmallow sauce.
Ruth ordered vanilla ice cream with fudge sauce.
Dave ordered mint ice cream with chocolate sauce.
Martin ordered chocolate ice cream with butterscotch sauce.
