A random number is picked following which, five guesses are to be made in order to find the correct number. All the guessed numbers are noted down in a paper. On another paper, all the differences between the guessed numbers and the picked numbers are written down by subtracting the smaller one from the bigger one. Now, one number each is erased from both of the papers. As a result, four numbers remain on each paper: Guesses: 27, 32, 44, 45 Differences: 5, 7, 10, 13 If this is all the information you need, can you find out what number was picked?
