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, C is to the right of D, and E is to the right of A. Who is standing in the middle? (2020)
Step 1: Identify the positions based on the clues given.
Step 2: The first clue says 'A is to the left of B'. This means A comes before B in the line.
Step 3: The second clue says 'C is to the right of D'. This means D comes before C in the line.
Step 4: The third clue says 'E is to the right of A'. This means E comes after A in the line.
Step 5: Now, let's put these clues together. We know A is before B, and E is after A, so we can write: A, B, E.
Step 6: We also know D is before C, so we can add D and C to our arrangement. Since D and C are not mentioned with A or B, we can place them in the middle: A, B, D, C, E.
Step 7: Now we have the full arrangement: A, B, D, C, E.
Step 8: To find who is in the middle, we look at the arrangement. The middle position in a line of five people is the third position.
Step 9: In our arrangement, the third person is D.
