In a seating arrangement, five friends are sitting in a row facing north. A is to the immediate right of B. C is to the left of D. E is between A and C. Who is sitting at the extreme left end?
B
D
A
E
D
Place the fixed anchor point first (A is to the immediate right of B) then chain the remaining elements by identifying the middle element between two people.
Place the fixed anchor point first (A is to the immediate right of B) then chain the remaining elements by identifying the middle element between two people.
Analyze initial constraints
Five friends (A, B, C, D, E) face north. Constraint 1: A is to the immediate right of B (B, A). Constraint 2: E is between A and C (A, E, C). Combined, this forms a sequence: B, A, E, C.
Place the final person
We have the sequence B, A, E, C. The final constraint is that C is to the left of D. Since only one spot remains, D must be to the immediate right of C: B, A, E, C, D.
Identify the extreme left position
Looking at the final order from left to right (B, A, E, C, D), the person at the extreme left end is B.
A is correct because the arrangement is B-A-E-C-D. Option B is incorrect as D is at the extreme right. Option C is incorrect as A is the second person from the left. Option D is incorrect as E is the middle person.
A is correct because the logical sequence B, A, E, C, D places B at the extreme left end of the row.
Always look for 'bridge' elements (people mentioned in two different clues) to link segments into a single linear sequence quickly.
