Directions: - These questions are based on the following data.
On which of the following day(s) of the week is it possible for Praful to make a single statement:
Where : P - I lied yesterday.
Q - I will lie tomorrow.
Let it be a day on which Praful is lying.
⇒ 3 cases are possible
~ (P and Q) ⇒ 1. ~P and ~Q
Case (1) is not possible as already seen in solution 158 but for the case (2) or (3) we get today is Mondey. Or today is a Wednesday.
Further if we take the case that Praful is speaking the truth i.e. both P and Q are true we see that it is not possible (from solution 158).
∴ Today can be a Mondey.
Directions: - These questions are based on the following data.
One day Umesh met two cousins of Praful – Archana and Rachna. One of them is like Praful– lying on Mondey, Tuesday and Wednesdays (and speaking truth on the other days of the week) and the other is like Karan – lying on Thursdays, Fridays and Saturdays (and speaking truth on the other days of the week) but Umesh does not know who is like Praful and who, like Karan. He also does not know what day of the week it is. They introduced themselves to him one by one:
If it any day Monday to Saturday to Saturday then exactly one out of Archana and Rachana is lying while the other is speaking the truth. For the given statements, it is required that both by lying OR both be speaking the truth. (Failing which the statements are clearly inconsistent). But as mentioned today cannot be a day for Mondey to Saturday since both cannot lie or speak the truth simultaneously. Therefore the only possibility being that today is a Friday and both are speaking the truth. ?the first one is Archana.
