If n is a positive integer, which of the following is a possible value of |71 - 5n| ?	Select the correct option
A) 7  B) 5  C) 19  D) 15  E) 20
When 71&gt;5n, then |71- 5n| = 71- 5n = (70-5n) + 1 = {multiple of 5} + 1   When 71&lt;=5n, then |71 - 5n| = -(71- 5n) = (5n-70) - 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: 19
