Seven people A, B, C, D, E, F, and G have meetings on different days of a week starting from Monday to Sunday. Only two people have meetings between A and C. F has a meeting on Wednesday. B has a meeting immediately after C. D has a meeting before A. How many people have meetings after G?

Fix the anchor point (F at Wednesday) and map the surrounding blocks (C, B) first to narrow down the limited possibilities for D and A.
Fix the anchor point (F at Wednesday) and map the surrounding blocks (C, B) first to narrow down the limited possibilities for D and A.
Establish the base grid
Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun. We are given F is Wednesday. The constraint 'Only two people between A and C' with 'B immediately after C' implies the blocks (C, B) or (A, _, _, C, B) or (C, B, _, _, A).
Applying constraints
If C is Mon, B is Tue, then A must be Thu (two people between A and C). This leaves E, D, G for Fri, Sat, Sun. D is before A, but if A is Thu, D must be earlier. D must be before A, and F is Wed. Placing D on Mon/Tue/Thu creates a conflict. Let's test the configuration: Mon: D, Tue: A, Wed: F, Thu: E, Fri: C, Sat: B, Sun: G. Here, two people are between A and C (F, E), and B follows C.
Final verification
Final sequence: Mon: D, Tue: A, Wed: F, Thu: E, Fri: C, Sat: B, Sun: G. All conditions satisfied: 1. Two between A and C (F, E). 2. F is Wed. 3. B immediately after C (Fri/Sat). 4. D before A. Result: G is on Sunday, so 0 people have meetings after G.
B is incorrect as only 0 people follow G. C is incorrect as only 0 people follow G. D is incorrect as only 0 people follow G.
A is correct because, based on the logical sequence D-A-F-E-C-B-G, G occupies the final day (Sunday), leaving no one after G.
In scheduling puzzles, always look for the most constrained variable first. If two people have a fixed gap between them, try placing the block in all valid positions immediately.
