Let’s start by consolidating all information available:
• We know we have 4 Economics, 3 Sociology, and 1 Anthropology student.
• 5 guides: P, R, and T guide 2 students each. Q and S guide one student each.
• Each student has guide belonging to same department.
• 4 slots: 9am, 9.30am, 10am, and 10.30am. Maximum 3 seminars in each slot. 

Seminars guided by same person never in same slot, always in consecutive slots.
Let’s create a table and fill all further information in it:
• From (1), Economics students have seminars in all 4 slots
• From (2), 10am has only one seminar by ‘A’, hence A must be Economics student
• From (3), 10.30 has another seminar of Anthropology. ‘F’ must be the only Anthropology student.
From (4), 9am has another seminar of Sociology.
• From (5), B & G have seminars in same slot. This slot cannot be either of the last 2 slots, since we
need 2 empty slots. Hence, B & G are scheduled at either 9am or 9.30 am.
• From (6), since P is guiding B & C, C must be a Sociology student too, and B & C must have
seminars in consecutive slots. Hence, C must be 9/9.30 depending on B’s slot.
• From (7), since A’s slot is 10, G (along with B) must be scheduled at 9.30am. Consequently, C
must be scheduled at 9am.
• We know identities of 3 Sociology and 1 Anthropology student, hence remaining must be
Economics students.
• Since Q & S guide 1 student each, they must be either of Anthropology or Sociology guides, and
must guide either of F or G. Hence, R & T are Economics guides.
• Since same guides must have consecutive slots, R must have 10 and 10.30 slots while T has 9 &
9.30 slots. 

• S may be guiding either of ‘F’ or ‘G’, so not necessarily true
• Similarly, Q may be guiding either of ‘F’ or ‘G’, so not necessarily true
• We are sure that ‘H’ is an Economics student, hence TRUE
• ‘B’ is scheduled in the second slot, hence False
