  • Question
  • How many four digits numbers greater than 6000 can be made using the digits 0, 4, 2, 6 together with repetition.


  • Options
  • A. 64
  • B. 63
  • C. 62
  • D. 60

  • Correct Answer
  • 63 

    Explanation

    Given digits are 0, 4, 2, 6

    Required 4 digit number should be greater than 6000.

    So, first digit must be 6 only and the remaining three places can be filled by one of all the four digits.

    This can be done by

    1x4x4x4 = 64

    Greater than 6000 means 6000 should not be there.

    Hence, 64 - 1 = 63.
