Solution Kites

Debbie's kite is number 2. She is 9 years old and the kid who is with their

grandfather is 10 (clue 1). David is 12 and his kite is number 1 (clue 2).

By elimination, Darren's kite is number 3 and he is 10 years old and (1),

he is with his grandfather. David isn't with his brother (2), so father. By

elimination, Debbie is with her brother.

Darren - 10 - grandfather - kite 3

David - 12 - father - kite 1

Debbie - 9 - brother - kite 2
