ANSWER
1-----They get one each. Grandfather, father, son. Two fathers, two sons, three loaves divided equally.
2----- it is in 4 measurements:
Separate the coins into 3 stacks of 9 (A, B, C). Weigh stack A against B and then A against C.
Take the stack with the different weight (note lighter or heavier) and break it into 3 stacks of 3 (D,
E, F). Weigh stack D against E. If D and E are equal, then F is the odd stack. If D and E are not
equal, the lighter or heavier (based on the A, B, C comparison) is the odd stack. You now have
three coins (G, H, I). Weigh G and H. If G equals H, then I is the odd and is lighter or heavier
(based on the A, B, C comparison). If G and H are not equal, then the lighter or heavier (based on
the A, B, C comparison) is the odd coin.
3-----3 1 2 2 1 1
1 3 1 1 2 2 2 1
REASON :BELOW STATEMENT DESCRIBES THE ABOVE
4-----Remove an item from box 3.
The item tells you what label to put on box 3.
Move the nails and screws label to the box labeled with the other item, and its label to the remaining box.
Example: you remove a nail from box 3.
Move the label nails from box 1 to box 3.
You can't move the nails and screws label to box 1: that would be a swap, and all three labels must be corrected.
Move it instead to box 2, and the screws label to box 1.
[box 1] screws
[box 2] nails and screws
[box 3] nails
5-----It is 1
