  • Question
  • How many 3 digit numbers are divisible by 6 in all?


  • Options
  • A. 149
  • B. 150
  • C. 151
  • D. 166

  • Correct Answer
  • 150 

    Explanation
    Required numbers are 102, 108, 114, ... , 996

    This is an A.P. in which a = 102, d = 6 and l = 996

    Let the number of terms be n. Then,

    a + (n - 1)d = 996

      ⟹ 102 + (n - 1) x 6 = 996

      ⟹ 6 x (n - 1) = 894

      ⟹ (n - 1) = 149

      ⟹ n = 150.
