Hint:

For complex logic puzzles, a grid or table is the best tool. List all entities (people, places, items) and use 'X' for negative information and '$\checkmark$' for positive information to systematically solve the puzzle.

Answer 1

The Correct Option is D

Step 1: Create an initial table.Create a table with columns for Friend, City, and Company.| Friend | City | Company ||--------|---------|---------|| A | | || B | | || C | Indore | || D | | |
Step 2: Populate the table with facts.1. C went to Indore. (Direct information)2. RR interviewed in Nagpur. This implies the Nagpur traveler was interviewed by RR.3. A did not go to Nagpur. (Given)4. Since C is in Indore, A is not in Nagpur, and the Nagpur person works for RR, A was not invited by RR.5. B did not go to Gurugram. (Given)6. A was not invited by PP or SS. (Given)7. B was not invited by RR or PP. (Given)
Step 3: Deduce who went to Nagpur.The cities are Indore, Noida, Gurugram, and Nagpur. C is in Indore, and A is not in Nagpur. The Nagpur person works for RR. B was not invited by RR, so B did not go to Nagpur.Therefore, by elimination, D went to Nagpur. D's company is RR.
Step 4: Determine companies for A, B, and C.- D's company is RR.- Remaining companies: PP, QQ, SS.- A was not invited by PP or SS, therefore A's company is QQ.- B was not invited by PP or RR (RR is D's company). Therefore B was not invited by PP.- Remaining companies for B and C are PP and SS. Since B was not invited by PP, B's company is SS.- By elimination, C's company is PP.
Step 5: Determine the remaining cities.- C is in Indore. D is in Nagpur.- Remaining cities for A and B are Noida and Gurugram.- B did not go to Gurugram. Therefore, B went to Noida.- By elimination, A went to Gurugram.Final Table:| Friend | City | Company ||--------|----------|---------|| A | Gurugram | QQ || B | Noida | SS || C | Indore | PP || D | Nagpur | RR |Answer to Q39: C's interview was scheduled in company PP.Answer to Q40: D went to Nagpur.
