    Question

    If the 6-digit number 589y72 is completely divisible by

    8, then the smallest integer in place of y will be:
    A 1 Correct Answer Incorrect Answer
    C 2 Correct Answer Incorrect Answer
    D 3 Correct Answer Incorrect Answer

    Solution

    For a number to be divisible by 8, the last three digits must be divisible by 8. Here, the last three digits are *72. Let's evaluate the values for *: If y = 0: 072 ÷  8 = 9 (divisible) • If y = 1: 172 ÷  8 = 21.5 (not divisible) • If y = 2: 272 ÷  8 = 34 (divisible) • If y = 3: 372 ÷  8 = 46.5 (not divisible) The smallest value of that makes the number divisible by 8 is 0.
