Answer:
You can solve this mystery by assuming every one of them as a hacker turn wise. Suppose Tim is the hacker. Then, his first and last statement will be lies. But that can’t be true as he can speak just one lie.
You will find the same result while assuming Clark, Mary and Betty as the hackers but will see that while assuming Bra as the hacker, only his first statement is false.
Thus Brad is the hacker.
