How many numbers, between 100 and 1000, can be formed with the digits 3, 4, 5, 0, 6, 7? (Repetition of digits is not allowed)

• At first place we can select 5 out of 6 numbers (Excluding 0)
  At second place we can select 5 again (Not repeating presvious one but including 0 this time)
  At third place we can select 4 out of remaining as we can't repeat 2 which we have already selected
  Hence....5*5*4=100
