Question

A boy and a girl make the following statements, of which at most one is correct:
The one in a white shirt says: I am a girl (statement-I)
The one in a blue shirt says: I am a boy (statement-II)
Which of the following is the correct inference?

The correct answer is
Both the statements I and II are incorrect

Logic Analysis: Statements Accuracy

The problem involves a boy and a girl making statements. The key constraint is that at most one statement is correct. We need to determine the validity of their statements based on this rule.

The statements are:

  • Statement-I (White Shirt): "I am a girl"
  • Statement-II (Blue Shirt): "I am a boy"

Evaluating Scenarios based on "At Most One Correct" Rule

We examine two possible assignments of shirts to the individuals:

Scenario 1: White Shirt = Boy, Blue Shirt = Girl

  • The boy (White Shirt) states: "I am a girl" (Statement-I). This is false.
  • The girl (Blue Shirt) states: "I am a boy" (Statement-II). This is false.

Result: Both statements are incorrect. This aligns with the rule that 'at most one statement is correct' (in this case, zero are correct).

Scenario 2: White Shirt = Girl, Blue Shirt = Boy

  • The girl (White Shirt) states: "I am a girl" (Statement-I). This is true.
  • The boy (Blue Shirt) states: "I am a boy" (Statement-II). This is true.

Result: Both statements are correct. This contradicts the rule that 'at most one statement is correct'. Therefore, this scenario is impossible.

Conclusion: Statement Correctness

Only Scenario 1 is consistent with the problem's conditions. In this scenario, the boy wears the white shirt and the girl wears the blue shirt, and importantly, both of their statements are false.

Thus, the correct inference is that both statements I and II are incorrect.
