Answer:
Elly -
History - AGO - 145
Christina
- Biology - PED - 123
David
- French - NET - 134
AI answer:
Let's analyze the clues and use the information to determine the word codes and number codes for each student.
1. AGO is the word code she uses but she does not study French.
- So, AGO belongs to Christina or Elly, but it cannot be associated with French.
2. Christina's word code does not start with N.
- Christina's word code is not NET.
3. The student with the number code 145 studies History.
- So, the student with 145 is studying History.
4. Elly's number code is more than the code of the student with the NET word code.
- Since Elly's number code is more than NET, and NET cannot be Christina's, Elly's number code is more than Christina's.
5. Christina's number code is less than the number code of the student studying French.
- So, Christina's number code is less than the number code associated with French.
Now, let's use these clues to deduce the word and number codes for each student:
- From clue 3, we know that the student with the number code 145 studies History.
- From clue 5, we know that Christina's number code is less than the number code for French.
- From clue 4, we know that Elly's number code is more than the code of the student with the NET word code.
Since Christina cannot have NET, Elly must have NET.
Let's represent the information:
- Christina: Word Code (X), Number Code (Y)
- David: Word Code (Z), Number Code (W)
- Elly: Word Code (NET), Number Code (More than X, Less than Y and Z)
Now, let's consider clue 2:
- Christina's word code does not start with N.
- So, Christina's word code is not NET.
Now, we can fill in the information:
-Christina: Word Code (AGO), Number Code (Y)
- David: Word Code (Z), Number Code (W)
- Elly: Word Code (NET), Number Code (More than AGO, Less than Z)
Now, let's use clues 4 and 5 to narrow down the possibilities:
- Since Elly's number code is more than AGO,
Elly's number code is greater than Y.
- Since Elly's number code is less than Z, Elly's number code is less than W.
So, the possibilities are:
- Christina: Word Code (AGO), Number Code (123)
- David: Word Code (Z), Number Code (W)
- Elly: Word Code (NET), Number Code (134)
Now, the remaining code:
- David's code must be PED, and W must be 145 (from clue 3).
So, the final assignments are:
- Christina: Word Code (AGO), Number Code (123)
- David: Word Code (PED), Number Code (145)
- Elly: Word Code (NET), Number Code (134)
These assignments satisfy all the given clues.
