SASMO 2027 · Grades 4-5 · SET 008 · Self-study Question 17

A blueberry cake was half eaten during the afternoon. Their mother asks three children. Ron says, “Harry ate the cake.” Harry says, “Ron lied.” Tony says, “I did not eat the cake.” Exactly one child tells the truth. Who ate the cake? Enter the name.

Puzzle interpretation: exactly one of Ron, Harry and Tony ate the missing portion; Harry is denying Ron’s statement about this cake.
