Four friends A, B, C, D went to four different cities Indore, Noida, Gurugram and Nagpur for interviews in four different companies PP, QQ, RR and SS but not necessarily in the same order. 'A' was not invited by PP. 'B' did not go to Gurugram and was not invited by RR and PP. RR conducted its interview in Nagpur. 'C' went to Indore. 'A' did not go to Nagpur and was not invited by SS.
This problem requires us to deduce which of the four friends (A, B, C, D) went to Nagpur for an interview, based on a set of given conditions. We can solve this using a process of elimination, often aided by a table.
Step-by-Step Solution for Nagpur Interviewee
Let's list the friends, cities, and companies, and then apply the constraints:
- Friends: A, B, C, D
- Cities: Indore, Noida, Gurugram, Nagpur
- Companies: PP, QQ, RR, SS
Applying the Constraints:
- Constraint: 'C' went to Indore.
- This immediately tells us C is assigned to Indore.
- Therefore, C did not go to Nagpur.
- Constraint: RR conducted its interview in Nagpur.
- This means the person who went to Nagpur was interviewed by company RR.
- Constraint: 'A' did not go to Nagpur.
- This eliminates A as the person who went to Nagpur.
- Constraint: 'B' did not go to Gurugram and was not invited by RR and PP.
- Since 'B' was not invited by RR, and RR conducted interviews in Nagpur, 'B' could not have gone to Nagpur. This eliminates B.
Deduction Table:
Let's track who could have gone to Nagpur:
| Friend | Could have gone to Nagpur? | Reasoning |
|---|---|---|
| A | No | Explicitly stated in the constraints ('A' did not go to Nagpur). |
| B | No | Not invited by RR, and RR conducted interviews in Nagpur. Therefore, B did not go to Nagpur. |
| C | No | Went to Indore. Indore is different from Nagpur. |
| D | Yes | A, B, and C have been eliminated. By elimination, D must be the one who went to Nagpur. |
Final Conclusion:
Based on the step-by-step elimination using the provided constraints:
- Friend A did not go to Nagpur.
- Friend B did not go to Nagpur (as they weren't interviewed by RR, which held interviews in Nagpur).
- Friend C went to Indore, not Nagpur.
- Therefore, Friend D must have gone to Nagpur.
The person who went to Nagpur is D.
Important Questions from Puzzle (Notes)
- Four individuals - P, Q, R and S - are suspects in a theft case. They make the following statements :
P says: "Q is guilty."
Q says: "R is guilty."
R says: "P is innocent."
S says: "I am innocent"
If it is known that exactly one of them is guilty, and only the guilty person lies (all innocent people tell the truth), then who is the guilty one? - In which company, C's interview was scheduled?
- What is the sum of the digits of the number Q?
- What is the sum of A and Q if A is smaller than B?
- There are five men - A, B, C, D and E, six women P, Q, R, S, T and Z. A, B, and R are advocates. S, Q, P, D and C are doctors and the rest are teachers. A team has to be selected from these eleven persons subject to the following conditions:
(I) A, P and Z have to be together.
(II) B cannot go with D or R.
(III) E and Q have to be together.
(IV) C and T have to be together.
(V) D and P cannot go together.
(VI) C cannot go with Q.
If the team formed consists of two male advocates, two lady doctors and one teacher, the members of the team can be:
