If n is a positive integer, which of the following is a possible value of |51 - 5n|? Select
A) 7
B) 1
C) 14
D) 15
E) 20
When 51&gt;5n, then |51 - 5n| = 51 - 5n = (50-5n) + 1 = {multiple of 5} + 1   When 51&lt;=5n, then |51 - 5n| = -(51 - 5n) = (5n-50) - 1 = {multiple of 5} - 1   So, the correct answer must be 1 greater or 1 less than a multiple of 5. Only C fits.   Answer: 14
