If @ is a binary operation defined as the difference between an integer n and the product of n and 5, then what is the largest positive integer n such that the outcome of the binary operation of n is less than 16?
Choose the correct option
A) 1 B) 2 C) 3 D) 4 E) 5
@(n) = 5n - n   We need to find the largest positive integer such that 5n - n &lt; 16.   Then 4n &lt; 16 and n &lt; 4.   The largest possible integer is n = 3.   The answer is 3.
