10. Last night it snowed! Harry and his friends met up with the other kids at the

park for the ﬁrst snowball ﬁght of the season. Since Harry and his friends were

on diﬀerent teams, they only managed to get one chance to hit their friends with

snowballs. Several hours later, all the boys were very wet, tired and hungry.

They headed back to Harry’s home for a drink and a snack, his mom’s fresh

baked cookies. Determine the full name of each boy, who was hit by who, what

each boy had to drink, and what kind of cookie each chose.

(a) Barry, whose last name wasn’t Horn, hit Nathaniel but he got hit by the

boy who had the oatmeal raisin cookies. The boy who got peanut butter

cookies didn’t hit Curtis.

(b) The snowball that hit Barry wasn’t thrown by Nathaniel, whose last name

wasn’t West. Randy Mann didn’t have milk with his cookies. The boy

whose last name was Jones didn’t have chocolate chip cookies.

whose last name was Horn had neither sugar cookies nor apple juice. The

boy who hit Harry had chocolate cookies.

(d) The boys who hit Nathaniel and Curtis had apple juice and orange juice to

drink, not necessarily in that order. Harry, whose last name wasn’t Horn,

didn’t hit Barry nor was he hit by Nathaniel.
