Questions & Step-by-Step Solutions

In a linear arrangement of five friends A, B, C, D, and E, A is to the left of B but to the right of C. D is to the left of E. Who is in the middle?
  • Step 1: Identify the first condition: A is to the left of B. This means A comes before B in the arrangement.
  • Step 2: Identify the second condition: A is to the right of C. This means C comes before A in the arrangement.
  • Step 3: Combine the first two conditions: Since C is before A and A is before B, we can arrange them as C, A, B.
  • Step 4: Identify the third condition: D is to the left of E. This means D comes before E in the arrangement.
  • Step 5: Combine the previous arrangement (C, A, B) with the new information (D is before E). We can place D before E, resulting in C, A, B, D, E.
  • Step 6: Now, count the positions: C is 1st, A is 2nd, B is 3rd, D is 4th, and E is 5th.
  • Step 7: Identify the middle position: In a line of five friends, the middle position is the 3rd position.
  • Step 8: Determine who is in the middle: The 3rd position is occupied by B.
