Crack person-city-profession grids with a table and cross-elimination using tick and cross marks.
🎯 Learning Objective
Crack person-city-profession grids with a table and cross-elimination using tick and cross marks.
💡 Concept
- Make a grid: people in rows, city and profession in columns
- Direct clues give a tick; negative clues give a cross
- One tick in a row or column turns every other cell of that line into a cross
- Bridge clues like 'the doctor lives in Patna' join two categories — park them till one side is fixed
- Two crosses among three options force the third cell to be a tick
✏️ Easy Example
Q. Amit, Bina and Chetan are from Delhi, Mumbai and Kolkata, one each. Bina is from Kolkata. Amit is not from Delhi. Which city is Amit from?
- Bina = Kolkata (direct clue)
- Amit is not Delhi and not Kolkata → Mumbai
- Chetan gets the remaining Delhi
Answer: Mumbai
🇮🇳 Real-Life Example
A TTE matching passenger names, coach numbers and destinations on the reservation chart does exactly this — one confirmed entry cancels a whole row of options.
📝 Exam-Level Example
Q. Ravi, Sita and Tarun live in Jaipur, Patna and Surat and work as doctor, teacher and engineer (one each, in some order). The doctor lives in Patna. Ravi lives in Jaipur. Sita does not live in Surat. Tarun is not the teacher. What is Tarun's profession?
- Ravi = Jaipur; Sita cannot take Surat → Sita = Patna, Tarun = Surat
- Bridge clue: the doctor lives in Patna → Sita is the doctor
- Tarun is not the teacher → Tarun = engineer (Ravi = teacher)
Answer: Engineer
🪄 Memory Trick
Finish ONE category completely first — usually the one with the most clues — then transfer through bridge clues. Never hop between two half-filled categories.
⚠️ Common Mistakes
- ❌ Attaching a bridge clue like 'the doctor lives in Patna' to a person too early
- ❌ Forgetting that one-each means no repeats in any column
- ❌ Leaving a forced tick unmarked after two crosses in a line
🏆 Exam Tips
- ✅ Negative clues are gold — two crosses force the answer
- ✅ After the grid fills, re-read every clue once; one contradiction means one wrong tick
📌 Summary
- Grid + tick/cross marks = the whole method
- A tick wipes its row and column
- Bridge clues connect categories — apply them late
- Two crosses out of three force the third
