Seven persons are standing in a row, facing North. A Journalist is to the immediate right of a Pharmacist and to the immediate left of a Teacher. An Advocate is to the immediate right of an Accountant. The Advocate and the Pharmacist have one person between them. The Teacher and a Doctor have two persons between them. An Architect and the Pharmacist have two persons between them.
What is the position of the Advocate with respect to the Teacher?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Fourth to the left
Facing North, a person’s right is the right side of the row. Number the places 1 to 7 from the left and start with the blocks of persons who stand together.
The Journalist is between the Pharmacist and the Teacher: the block Pharmacist, Journalist, Teacher stands in three places in a row
The Advocate is to the immediate right of the Accountant: the block Accountant, Advocate
The Advocate is two places from the Pharmacist. Two places to the right of the Pharmacist is the Teacher, so the Advocate is two places to the left of the Pharmacist, and the Accountant one more place to the left
So the Pharmacist is in place 4 or 5. If the Pharmacist is in place 5, the order is Accountant 2, Advocate 3, Pharmacist 5, Journalist 6, Teacher 7; the Architect must be three places from the Pharmacist, in place 2 or 8, and neither is free. This case fails
So the Pharmacist is in place 4: Accountant 1, Advocate 2, Pharmacist 4, Journalist 5, Teacher 6
The Doctor is three places from the Teacher (place 3 or 9): Doctor in place 3. The Architect is three places from the Pharmacist (place 1 or 7): Architect in place 7
The Advocate is in place 2 and the Teacher in place 6: the Advocate is fourth to the left of the Teacher
