MATHS PUZZLE # 7 FIRST LEG (Second Year)

(from the 15th to the 22nd of November 2010) 

SUBJECT-IVE  DECISION
Last Summer four Comenius students called Kovács, Müller, Dvořák and González attended an international school, the Collège Sirondi. Each of them took 2 different subjects. Furthermore:
-Three students chose English.
-There was only one student who did Chemistry.
-Two students chose Mathematics.
-Two students, Sophia and the one called González took History.
-Natálie did not study English.
-Dávid chose Mathematics.
-The student called Dvořák did not do any course which was attended by either Pablo or by the student called Müller.
WHAT IS THE FULL NAME OF EACH STUDENT AND WHICH TWO SUBJECTS DID EACH LEARN? The following chart may help you record the information from the clues.

SOLUTION

Since Natálie was the only one that did not take up English and Dvořák did not do any course attended by either Pablo or Müller, it follows that Natálie and Dvořák were the same person and that she chose at least Maths.

Sophia and González did History and were among the three students who learnt English. Natálie Dvořák therefore did Maths and Chemistry.

Because Dávid was also a Maths student, he could not be  González so both Sophia and Pablo studied English and History.

As Sophia and González were two different students, it is clear that Pablo’s surname was González and Sophie´s was Müller, our fourth student being thus Dávid Kovács.

SO

Natálie	Dvořák	Maths	Chemistry
Pablo	González	English	History
Sophia	Müller	English	History
Dávid	Kovács	English	Maths
