Question 11
MediumOriginal questionFive colleagues, Kavya, Rohit, Sana, Anirudh and Pooja, each work in a different department (Legal, Design, Accounts, Sales or HR) and each reach the office by a different mode (metro, bicycle, car, bus or scooter). The following is known:
1. The colleague in Design cycles to work.
2. Sana comes by car, but she does not work in Sales.
3. Kavya comes by neither bus nor bicycle, and she works in neither HR nor Accounts.
4. The colleague in Sales takes the bus.
5. Pooja rides a scooter.
6. Anirudh does not cycle to work.
7. Sana does not work in HR.
Which colleague works in HR?
Show the answer and explanation
Correct answer: A
Explanation
Sana comes by car (clue 2) and Pooja by scooter (clue 5).
Kavya uses neither the bus nor the bicycle (clue 3), so Kavya takes the metro. Bus and bicycle are left for Rohit and Anirudh; Anirudh does not cycle (clue 6), so Anirudh takes the bus and Rohit cycles.
The cyclist works in Design (clue 1), so Rohit is in Design; the bus user is in Sales (clue 4), so Anirudh is in Sales.
Kavya is not in HR or Accounts (clue 3), so Kavya is in Legal. Sana is not in HR (clue 7), so Sana is in Accounts and Pooja is in HR.
Pooja works in HR.
Worth noting
Clue 7 is small but decisive: without it, Sana and Pooja could swap Accounts and HR.
