Logic Problem Solution:
The Leap Year Club

From the introduction, the five members of the Leap Year Birthday Club were born in five consecutive leap years, each on a different February 29 from 1944-1960. By clue 2, Silva, Linda, and Mr. Watson were born in three consecutive leap years. By clue 5, Kathy was born four years before Mr. Davis. There is no way for the information in the two clues to overlap, so all five celebration attendees are named between the two clues: either Kathy was born in 1944 and Silva in 1952, or Silva is the oldest and Kathy's birth year is 1956. Trying the first case, the five would have been born in order every four years as follows: Kathy, Mr. Davis, Silva in 1952, Linda, and Mr. Watson. John wasn't born on Feb. 29, 1952 (3), and Ted isn't Silva (4); so Bob would be Silva. However, he was born four years after Harkness (1), not Davis. So, the five were born in order Silva (1944), Linda (1948), Mr. Watson (1952) (2), Kathy (1956), and Mr. Davis (1960) (5). Bob isn't Watson (6); by clue 1, then, he is Davis and Kathy Harkness. By elimination, Linda is Moore. John is Silva and Ted Watson (3). The five members who attended the Leap Year Birthday event last night are

• John Silva, 1944
• Linda Moore, 1948
• Ted Watson, 1952
• Kathy Harkness, 1956
• Bob Davis, 1960
