Seven teachers, Arjun, Bilal, Ehsan, Hamza, Lubna, Omar and Rafiq, each give one lecture on a different day of the same week, from Monday to Sunday. Ehsan’s lecture is on a day before Lubna’s lecture. Exactly three lectures are held between the lectures of Rafiq and Lubna. Arjun’s lecture is on some day after Ehsan’s lecture, but not on the very next day. Only one lecture is held between the lectures of Omar and Bilal. Ehsan’s lecture is on the day immediately after Omar’s lecture. Arjun’s lecture is on a day before Hamza’s lecture. On which day is Arjun’s lecture?
