Six teachers, Arjun, Lalit, Sana, Usman, Vikram and Yasmin, each give one lecture on a different day of the same week, from Monday to Saturday. Arjun’s lecture is on some day after Vikram’s lecture, but not on the very next day. Only one lecture is held between the lectures of Vikram and Arjun. Lalit’s lecture is on Monday. Only one lecture is held between the lectures of Sana and Vikram. Vikram’s lecture is on a day before Yasmin’s lecture. Whose lecture is on the day immediately after Sana’s lecture?
Correct answer B. Usman
Explanation
From Monday to Saturday the only valid order is Lalit, Sana, Usman, Vikram, Yasmin, Arjun. Hence Usman's lecture comes the day after Sana's.
