Based on the analysis for the previous question, we have to determine the start of the schedule.
The constraints are:
If the schedule starts with C, D, or E, it's difficult to fit the BD and AE pairs.
Let's try starting with B. If B is first, D must be second (from BD pair). Schedule: B, D, _, _, _, _.
This start is consistent with both valid schedules we found in the previous question.
Schedule 1: B, D, C, BREAK, A, E
Schedule 2: B, D, BREAK, C, A, E
In all possible valid arrangements, the first drama to be staged is B.
A, B, C, D, E, F and G are travelling in three different vehicles: Swift, Creta, and Nexon. There are at least two passengers in each vehicle. Among them, only two are male. There are two engineers, two doctors and three teachers.
(i) C is a lady doctor and she does not travel with A and F, who are sisters.
(ii) B, a male engineer, travels with only G, a teacher, in a Swift.
(iii) D is a male doctor.
(iv) Two persons belonging to the same profession do not travel in the same vehicle.
(v) A is not an engineer and travels in a Creta.
(vi) The pair of sisters A and F travels in the same vehicle.
What is the profession of F?
