### On one fine day I met 3 person X, Y and Z each of them belongs to a different tribe i.e. Truth tellers, Liars, and Alternators. It is known that the truth tellers speak truth; liars speak lies and alternator alternates between truth and lies. Each of them gives 2 replies when asked their introduction.X: B is the liar, I am the truth tellerY: I am not the liar, C is the truth tellerZ: A is not the Truth teller, I am not the liarWho among the following is a liar?

• A.

X

• B.

Y

• C.

Z

• D.

Cannot be determined

B. Y
Explanation
Based on the given information, we can analyze the statements made by each person. X claims that B is the liar and that he is the truth teller. If X is the truth teller, then his statement about B being the liar would be true, which contradicts the fact that truth tellers always speak the truth. Therefore, X must be lying. Z claims that A is not the truth teller and that he is not the liar. If Z is the truth teller, then his statement about A not being the truth teller would be true, which contradicts the fact that truth tellers always speak the truth. Therefore, Z must be lying. Y claims that he is not the liar and that C is the truth teller. If Y is telling the truth, then his statement about C being the truth teller would also be true, which is consistent with the fact that truth tellers always speak the truth. Therefore, Y must be the liar.

### Ram and Shyam just became friends with Mohan, and they want to know when her birthday is. Mohan gives them a list of 10 possible dates:1. May 15 May 16 May 192. June 17 June 183. July 14 July 164. August 14 August 15 August 17Mohan then tells Ram and Shyam separately the month and the day of her birthday respectively.Ram: I don’t know when Mohan’s birthday is, but I know that Shyam does not know too.Shyam: At first I don’t know when Mohan’s birthday is, but I know now.Ram: Then I also know when Mohan’s birthday is.So when is Mohan’s birthday?

• A.

May 15 May 16 May 19

• B.

June 17 June 18

• C.

July 14 July 16

• D.

August 14 August 15 August 17

C. July 14 July 16
Explanation
Ram says that he knows that Shyam also doesn't know when Mohan's birthday is. This implies that Mohan's birthday cannot be on May 19 or June 18 because those dates are unique in the list. Shyam says that now he knows when Mohan's birthday is. This means that Mohan's birthday must be on a date that is not unique. The only date left that is not unique is July 16. Therefore, Mohan's birthday is on July 16.

• A.

Corporate planning

• B.

Strategic marketing planning

• C.

Market intelligence

• D.

Marketing research

A. Corporate planning
Explanation
Corporate planning is neither an input nor an output to a MkIS. A marketing information system consists of inputs, which are the data and information collected from various sources such as market research and market intelligence. These inputs are processed and analyzed to generate outputs, which are the insights and reports that help in making strategic marketing plans. Corporate planning, on the other hand, is a separate process that involves setting goals, formulating strategies, and making decisions at the organizational level. While it may utilize information from a MkIS, it is not directly part of the inputs or outputs of the system.

### Which of the following is not a principal issue in service encounter design?

• A.

Technology and information support systems

• B.

Customer contact behaviour and skills

• C.

Service provider selection, development and empowerment

• D.

Service recovery and guarantees

A. Technology and information support systems

The principal issues in service encounter design include customer contact behavior and skills, service provider selection, development and empowerment, and service recovery and guarantees. These factors are more directly related to the interaction between the customer and the service provider and have a greater impact on the overall service experience.
