      then find the maximum value of 8x.
      A 56 Correct Answer Incorrect Answer
      B 64 Correct Answer Incorrect Answer
      C 72 Correct Answer Incorrect Answer
      D 80 Correct Answer Incorrect Answer

      Solution

      We know that a number is divisible by 3 only when the sum of its digits is also divisible by 3. So,
      8 + 6 + 4 + x + 1 + 2 = (21 + x) should be divisible by 3 So, possible values of x = 0, 3, 6, 9 Maximum possible value of x = 9 So, required value
      = 8 Ă— 9
      = 72
