Five girls are not in complete agreement about the date of the Math test.
Andrea says it will be in August, 16th, Monday;
Daniela says it will be in August, 16th, Tuesday;
Fernanda says it will be in September, 17th, Tuesday;
Patricia says it will be in August, 17th, Monday;
Tatiane says it will be in September, 17th, Monday.
Only one of them is completely right. The others guessed at least one of these information correctly: the month, the day or the weekday.
Who is right?
