Question 121
P, Q and R gave the following statements:
P - “Either it is day or it is night”.
Q - “It is night”.
R - “It is neither day nor night”.
Of these people, only one is wrong.
What time of the day is it?
Solution
Case 1: P is wrong.
According to Q, it is night but according to R, it is neither night nor day which means that they both can't be true together. So, this case is not possible.
Case 2: Q is wrong.
Again, statements of P and R can not exist together, so this case is also not possible.
Case 3: R is wrong.
According to the statements of P and Q, it is night and this conclusion is supported by both the statements.
Thus, the answer is Option D.
