There are Seven Lecturers – Bhaskar, Bharti, Manu, Vidhi, Vansha, Sukant, and Deepak. They teach seven subjects, viz., Maths, Zoology, Botany, Chemistry, Physics, English and Statistics on one day in a week starting from Monday and ending on Sunday (of the same week). There will be separate timings for each lecture and the number of hours for each lecture can be 1hr, 2hr, 3hr, 4hr and 5 hr. Note: Total hours taken by all the lecturers = 18 hours. There are two such cases where the duration of the lectures given by two lecturers is same. Chemistry is taught on Thursday. English is neither taught on Tuesday nor on Saturday. The Botany professor gave lecture immediately after lecturer Bhaskar. Bharti is not a Chemistry Professor. Maths is taught for one hour. The Professor Bharti gave his lecture on one of the days before Friday. Neither professor Vansha nor professor Sukant gave his lecture on Sunday. Professor Sukant gave his lecture immediately after Vansha. Lecturer Bhaskar spent more time than Lecturer Manu. Time taken by lecturer Manu is the sum of time taken by the lecturers Bharti and Sukant. Subjects Maths & Zoology are taught for same duration. The lecturer who took maximum time is immediately preceded by the person who took less than one hour of maximum time. The difference between durations of lectures of the subjects taught on Friday and Sunday is equal to the time taken by the lecturer Bhaskar. Professor who gave maths lecture is immediately preceded and followed by Manu and Deepak respectively. Professor who gave lecture on Sunday spent less than three hours. Only one lecture is held between Chemistry and Botany. There are two lectures between the lectures of Zoology and Math. Zoology is taught after Math. Statistics is neither taught on Monday nor on Sunday. Botany is not taught on the immediate next day on which Zoology is taught. Physics is taught on Monday.
