Grant, Neal and Kyle just finished their lunch. One of the boys had a ham sandwich, another a turkey sandwich and the third, a chicken sandwich.
If only one of the following four statements is true, who had what for lunch?
1. Kyle had the turkey sandwich.
2. Neal did not have a chicken sandwich.
3. Kyle did not have a chicken sandwich.
4. Neal did not have the ham sandwich.
If 1 is True then 3 is True, so 1 is not it.
1 is False
Kyle did not have turkey.
If 3 is True, then Kyle had either turkey or ham, but not turkey, therefore ham.
From 2, Neal had chicken, but this makes 4 True.
3 is False
Kyle had chicken
2 must be False because we know Kyle had chicken

If 4 is True, then Neal had ham;
We already know Kyle had chicken;
Grant then had turkey.
