Questions & Step-by-Step Solutions
Five people A, B, C, D, and E are standing in a line. A is to the left of B, and C is to the right of D. If E is standing at the end of the line, who is in the middle? (2023)
Step 1: Identify the people involved: A, B, C, D, and E.
Step 2: Understand the positions: A is to the left of B, which means A comes before B in the line.
Step 3: Understand the second position: C is to the right of D, which means D comes before C in the line.
Step 4: Note that E is at the end of the line, meaning E is either at the far left or far right.
Step 5: Since E is at the end, we can place E at the far right for this arrangement.
Step 6: Now we have E at the end, and we need to arrange A, B, D, and C in the remaining positions.
Step 7: Place A and B together since A is to the left of B. So we can have A, B.
Step 8: Now we need to place D and C. Since D must be before C, we can place D before C.
Step 9: A possible arrangement is A, B, D, C, E.
Step 10: In this arrangement, the middle position (3rd position) is occupied by B.
Relative Positioning – Understanding the relative positions of individuals based on given constraints.
Logical Deduction – Using logical reasoning to deduce the arrangement of individuals in a line.
