Crack GMAT (diagnostic test)

1) If I am meeting the principal and the vice-principal, I am visiting the school.

2) If I am meeting the principal but not the vice-principal, I am not visiting the school.

3) If I am not visitng the school, I am not meeting the principal and the vice principal.

(A) I only

(B) II only

(C) III only

(D) I and II only

(E) II and III only

1) If I am meeting the principal and the vice-principal, I am visiting the school.

I could be meeting them out of the school. so not true.

2) If I am meeting the principal but not the vice-principal, I am not visiting the school.

If I visit the school, I meet both. If I am not meeting both, then I am not visiting the school. I am meeting the principal somewhere else out of the school. True.

3) If I am not visitng the school, I am not meeting the principal and the vice principal.

I could be meeting both somewhere else other than school. so not true.

Only B.
