CLUE 1: David’s friend is a girl. She isn’t eight years old. She isn’t his cousin or his neighbour.
Step 1: David’s friend is a girl.
You can cross out (-) Marty and Ted in David’s row.
Step 2: She isn’t eight years old.
You can cross out 8 in David’s row.
Step 3: She isn’t his cousin or his neighbour.
You can cross out the cousin and the neighbour in David’s row.
CLUE 2: Marty is Cindy’s friend. He isn’t her classmate. He’s nine years old.
Step 1: Marty is Cindy’s friend.
You can put an X to Marty in Cindy’s row. You can cross out Amy, Lisa and Ted.
Of course you can cross out Anne and Brian in Marty’s column.
Step 2: He isn’t her classmate.
You can cross out the classmate in Cindy’s row and also in Marty’s column.
Step 3: He’s nine years old.
• You can put an X to 9 in Cindy’s row. You can cross out here 7, 8 and 10. In the column 9 you can
cross out Anne, Brian and David.
• You can put an X to 9 in Marty’s column. You can cross out here 7, 8 and 10.
• And you can also cross out Amy, Lisa and Ted in row 9.
Step 4: You can cross out one more thing in row 9. It’s the classmate. Because Marty isn’t Cindy’s classmate.

CLUE 3: The neighbours are girls.
• You can cross out Brian and Cindy in the neighbour’s column. Yes, Cindy, too. Because we know her
friend is a boy.  So there’s only one name left. It’s Anne. So Anne’s neighbour is her best
friend. You can put an X to Anne in this column, and cross out the classmate, the cousin and the
family friend in Anne’s row.
• You can also cross out 9 in the neighbour’s column (because Marty’s 9 and he’s a boy). And you can
also cross out Marty and Ted in the neighbour’s row.
• You can cross out Ted in Anne’s row.
•  Now you get Ted’s Brian’s friend. Put there an X.
• Cross out Amy and Lisa in Brian’s row.
CLUE 4: Lisa is a family friend.
•
Put an X to the family friend in Lisa’s column. You can cross out the classmate, the cousin and the
neighbour. You can also cross out Amy, Marty and Ted in the family friend’s row.
•
You get that Amy is a neighbour. Put an X there. Cross out the cousin and the classmate in Amy’s
column.
•
Now you get that Ted is the classmate and Marty’s the cousin. Put there X. Cross out the cousin
in Ted’s column.
•
Use these pieces of information to fill in the other parts of the table. Let’s see how.
o So Ted’s the classmate and he’s Brian’s friend, too. That’s why we can put an X to the
classmate in Brian’s row and cross out the cousin and the family friend. Also we can cross
out David in the classmate’s column.
o We get that Cindy’s friend is her cousin. Put there an X. Cross out the family friend in her
row.
o And also we know now David’s friend is the family friend. Put there an X, as well.

•
The next step is to match the pieces of information we know.
o The neighbour is Amy and Anne’s friend is the neighbour. So Amy is Anne’s friend. Put
there an X. And cross out Lisa in Anne’s row and David in Amy’s column.
o There’s only one possibility, Lisa is David’s friend, so put an X to Lisa in David’s row.
She’s very young.
• Put an X to 7 in Lisa’s column (because very young means the youngest here) and cross out 8 and
10. Also cross out Amy and Ted in the row of 7.
• Lisa is David’s friend, so put an X to 7 in David’s row. Cross out 10. Also cross out Anne and Brian
in the column of 7.
• Lisa is a family friend, so put an X to the family friend in the row of 7. Cross out here the
classmate, the cousins and the neighbours. Also cross out 8, 9, 10 in the family friend’s column.
• There’s only one possibility in the row of 9, so put an X to 9 in the cousin’s column and cross out 8
and 10.
CLUE 5: Ted isn’t ten.
• Cross out Ted in row of 10. We get that Amy is 10. So put there an X. Cross out 8 in Amy’s column.
We get that Ted’s 8. Put there an X.
• Finally, put an X to 10 in Anne’s row and another one to 8 in Brian’s.
• Put an X to the classmate in row of 8 and one more to the neighbour in the row of 10. Cross out
the left rubrics.
We are ready. You can fill in the chart / table with the pieces of information and write down the sentences.
