for some reason this is in my SAT prep book (my score is horrible anyway):
Winkin said "We're all liars," Blinkin replied,"Only you are liar," and Finkin said "You're both liars," If each of them always tells the truth or always lies, how many of the three are liars?
the prep book doesn't have an answer for that question so does anyone know the answer? thanks
2 of the 3 (winkin and blinkin) are liars
winkin is a liar because if he always tells the truth, then's he's a liar, since he says they're all liars
blinkin is a liar because he says *only* winkin is a liar, but either blinkin or finkin is also a liar, since finkin says *both* winkin and blinkin are liars
finkin must be telling the truth, because winkin is a liar when he said they're all liars.
and your welcome. if you see a problem like this on an SAT, save it for last. ;-)
Nice bit o' logic there, yit!
