Five senior officers—Aditya, Bina, Chitra, Dev, and Esha—are assigned to inspect five distinct infrastructure projects: Metro, Bridge, Highway, Airport, and Port. Each officer belongs to either the Urban Development department or the Transportation department. The allocation follows these conditions:
1. Exactly two officers belong to Urban Development and three belong to Transportation.
2. Aditya and the officer inspecting the Airport both belong to Urban Development.
3. Chitra inspects the Bridge project and belongs to the same department as Aditya.
4. Bina and Dev belong to the Transportation department.
5. Dev is not assigned to inspect the Port or the Highway.

Based on the given information, who among the following officers is assigned to inspect the Metro project?

  1. DevAnswer
  2. B
    Aditya
  3. C
    Chitra
  4. D
    Bina

Answer

Dev is assigned to inspect the Metro project.
By resolving department constraints, Aditya and Chitra fill both Urban Development slots (Airport and Bridge respectively). Dev, Bina, and Esha are in Transportation and must be assigned to Metro, Highway, and Port. Since Dev cannot take Port or Highway, he must take the Metro project.

Step-by-Step Solution

1
Determine department membership for all officers.
Aditya and Chitra belong to Urban Development; Bina, Dev, and Esha belong to Transportation.
Aditya is given as Urban Development, and Chitra belongs to the same department. Since only two officers belong to Urban Development, the remaining three (Bina, Dev, Esha) must belong to Transportation.
2
Assign projects to the Urban Development officers.
Chitra is assigned to the Bridge project, and Aditya is assigned to the Airport project.
The officer assigned to the Airport belongs to Urban Development. Since Chitra inspects the Bridge, Aditya must inspect the Airport.
3
Assign the remaining projects (Metro, Highway, Port) to the Transportation officers (Bina, Dev, Esha).
Dev is assigned to the Metro project.
Dev cannot be assigned to the Port or the Highway. Out of the three available projects for Transportation officers, Metro is the only remaining possibility for Dev.
