Five persons are standing in a straight line and facing in the same direction. At one of the extreme end, there is a Doctor and at the other extreme end, there is a Lawyer. A Marketing Officer is standing to the right of a girl. An Author is to the left of the Lawyer. The girl is standing between the Doctor & the Marketing Officer. Counting from the left, determine that the Marketing Officer is at which place in the group?

Solution

✅ Correct Option: 4

Let the five positions in the line be numbered 1, 2, 3, 4, 5 from left to right.

Since Doctor is at one extreme and Lawyer at the other extreme, they occupy positions 1 and 5.


Since Author is to the left of the Lawyer, the Lawyer cannot be at position 1 (leftmost).

Therefore:

  • Lawyer is at position 5
  • Doctor is at position 1

The girl is between the Doctor and the Marketing Officer, and the Marketing Officer is to the right of the girl.

This gives the arrangement: Doctor ... Girl ... Marketing Officer

Since Doctor is at position 1, and Marketing Officer is to the right of the girl, we have:

Doctor (position 1) — Girl — Marketing Officer


Author must be to the left of the Lawyer (position 5), so Author can be at positions 2, 3, or 4.

Testing the arrangement where:

  • Girl is at position 2
  • Marketing Officer is at position 3
  • Author is at position 4

This gives: Doctor(1), Girl(2), Marketing Officer(3), Author(4), Lawyer(5)


Verifying all conditions:

  • Doctor at extreme end (position 1) ✓
  • Lawyer at other extreme end (position 5) ✓
  • Marketing Officer (3) is to the right of girl (2) ✓
  • Author (4) is to the left of Lawyer (5) ✓
  • Girl (2) is between Doctor (1) and Marketing Officer (3) ✓

The Marketing Officer is at position 3 from the left.

Therefore, the answer is Option 4: Third.
