Anybody know where I can find more logic problems?

[PhyIsOhSoHard]

I would like to practice logic thinking more. The sort of problems I'm talking about are like this:

Define two constraints, which relates the variables x and y to v such that if either x or y is 1 then v is forced to be 1.

Where the answer is then:
x ≤ v
y ≤ v

Does anybody know where I can find similar problems? Along with the answers to test and see if I solved correctly? Thanks!

Hi PhyIsOhSoHard:

I don't know any sources of the type of logic problems your describe, but you might find the following entertaining.

The following lists other great puzzle books by Smullyan

x ≤ v
y ≤ v

How do these constraints imply that if either x or y is 1 then v is 1? Let x = 1, y = 0. Both constraints are satisfied if v = 3.
