only that is not connected to

Type 1-1 Number Puzzles p.10~p.11 1. Write 5 in A, the only that is D E

not connected to 6. Then write 3 F

1 The numbers in F and H are 1 and 2 to satisfy in C, the remaining that is not connected to 1

or 2. Finally, place the last number 4 in D.
2 If F 1 and H 2, G H 6 implies that G 4,
and E F G H 17 implies that E 10. But, 5
each value can only be a number from 1 to 9, 13
which means that our assumption (F 1, H 2) is
wrong. Therefore F 2 and H 1. G H 6 46
implies that G 5, and E F G H 17 implies 2
that E 9.
