Solution: If we look at the second statement of B, we can start with the premise that B is an alternator and his first and third statements are false and second statement is true. He alternated in the order FTF (False, True, False).
If D’s first statement is true, then the second statement of A will be true. Therefore, A, D and C will all have atleast one true statement.
None of D, A and C can be a liar, which contradicts the condition that atleast one person is a liar.
Therefore, this case is not possible.
Hence, D’s first statement is false.
Now, from the second statement of A, we can say that at most one of A and C can be a truth teller.
As neither B nor D is a truth teller, there is only one truth teller between A and C.
D’s second statement must be false. Since, D’s first and second statement is false, his third statement also has to be false.
Therefore, D has to be a liar.
Now, if A is a truth teller, then B’s first statement is “C is either a Journalist or a Doctor” and this statement is false, since B’s first statement is false.
Also, B is an Engineer. C is a Banker.
A and D are Journalist and Doctor in any order.
If A is a Doctor, then D is a Journalist, in which case, C’s first statement is true and third statement is false, which is not possible according to their tribes. If A is a Journalist and D is a Doctor, then C’s first statement is false and third statement is true, which is also not possible according to their tribes. A cannot be a truth teller. C is a truth teller.
A is a Doctor and D is a Banker.
Also, from the third statement of D, C is an Engineer. B is a Journalist.
As third statement is false. Also, As second statement is false as C is a truth teller.
Hence, B is an alternator with the order of the statements as FTF, A and D are liars and C is a truth teller.
If D’s first statement is true, then the second statement of A will be true. Therefore, A, D and C will all have atleast one true statement.
None of D, A and C can be a liar, which contradicts the condition that atleast one person is a liar.
Therefore, this case is not possible.
Hence, D’s first statement is false.
Now, from the second statement of A, we can say that at most one of A and C can be a truth teller.
As neither B nor D is a truth teller, there is only one truth teller between A and C.
D’s second statement must be false. Since, D’s first and second statement is false, his third statement also has to be false.
Therefore, D has to be a liar.
Now, if A is a truth teller, then B’s first statement is “C is either a Journalist or a Doctor” and this statement is false, since B’s first statement is false.
Also, B is an Engineer. C is a Banker.
A and D are Journalist and Doctor in any order.
If A is a Doctor, then D is a Journalist, in which case, C’s first statement is true and third statement is false, which is not possible according to their tribes. If A is a Journalist and D is a Doctor, then C’s first statement is false and third statement is true, which is also not possible according to their tribes. A cannot be a truth teller. C is a truth teller.
A is a Doctor and D is a Banker.
Also, from the third statement of D, C is an Engineer. B is a Journalist.
As third statement is false. Also, As second statement is false as C is a truth teller.
Hence, B is an alternator with the order of the statements as FTF, A and D are liars and C is a truth teller.
Hence, option 2.
