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 A

Step 1: Create a table to organize the information. Let's make a table with columns for Friend, City, and Company. | Friend | City | Company | |--------|---------|---------| | A | | | | B | | | | C | Indore | | | D | | |
Step 2: Fill in the table with direct and deductive information. 1. C went to Indore. (Directly given) 2. RR conducted its interview in Nagpur. This means the person who went to Nagpur was interviewed by RR. 3. A did not go to Nagpur. (Given) 4. Since C is in Indore and A is not in Nagpur, and the person in Nagpur 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 the person who went to Nagpur. The cities are Indore, Noida, Gurugram, Nagpur. C is in Indore. A is not in Nagpur. Let's see who could be in Nagpur. The person in Nagpur works for RR. B was not invited by RR, so B did not go to Nagpur. Therefore, by elimination (D must have gone to Nagpur). And D's company is RR.
Step 4: Deduce the companies for A, B, and C. - D's company is RR. - Companies left: PP, QQ, SS. - A was not invited by PP or SS. So, A's company must be QQ. - B was not invited by PP or RR. RR is taken by D. So B was not invited by PP. - Companies left for B and C are PP and SS. Since B was not invited by PP, B's company must be SS. - By elimination, C's company must be PP.
Step 5: Deduce the remaining cities. - C is in Indore. D is in Nagpur. - Cities left for A and B are Noida and Gurugram. - B did not go to Gurugram. Therefore, B must have gone to Noida. - By elimination, A must have gone 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.
