The students are A and B. The teacher thinks of 2 positive integers and tells the sum of those numbers to student A without student B hearing it. Then tells their product to student B without student A hearing it. After this, the teacher asks the 2 students what was the 2 numbers. First student A says: I don't know. Then student B says: I don't know either. After hearing this, student A says: Now I know. Then student B says: Now I know them too. What were the 2 numbers?
Combination Lock Riddle2020-04-30T00:00:00+00:00/combination-lock-riddleA combination for a lock has 3 wheels, X, Y, and Z, each of which can be set to eight different positions. The lock is broken and when any two wheels of the lock are in the correct position, the lock will open. Thus, anyone can open the lock after 64 tries (let A and B run through all possible permutations). However, the safe can be opened in fewer tries! What is the minimum number of tries that can be guaranteed to open the lock?
