A number from 1 to 100 has been chosen. You may ask only questions answered 'yes' or 'no'. What is the least number of questions that guarantees finding the number?
सही उत्तर: क) 7
Each answer can at best halve the possibilities. 6 questions distinguish only 2⁶ = 64 cases, while 7 distinguish 2⁷ = 128 ≥ 100, so 7 questions are needed and enough.

Each of A, B and C is either a truth-teller (always truthful) or a liar (always lies). A says, 'B is a liar.' B says, 'C is a liar.' C says, 'A and B are truth-tellers.' Who is a truth-teller?
सही उत्तर: ख) B only
A and B cannot both be truthful (A calls B a liar), so C's statement is false and C is a liar. Then B, who says C is a liar, is truthful, and A, who calls B a liar, is lying. Only B tells the truth.
