A number is picked, and five guesses are made to find this number. The guesses are written on a paper, and the differences between the guesses and the picked number (by subtracting the smaller from the bigger) are written on another paper. Later one number is randomly erased from each paper. As a result there are 4 numbers on each paper.

Guesses: 27, 32, 44, 45
Differences: 5, 7, 10, 13

If this is all the information needed, what is the number?
