How many vehicle registration plate numbers can be formed with digits 1,2,3,4,5(no digits being repeated)if it is given that registration number can have 1 to 5 digits ?


options:
205 100 325 105

• you can have registration plates of 5,4,3,2 or 1 digits
  So, it's 5*4*3*2*1 + 5*4*3*2 + 5*4*3 +5*4 + 5
  =120 + 120 + 60 + 20 +5
  => 325

• as we can registration of 5 digit or 4 or 3 or 2 or 1
  so
  for 5 digit->5*4*3*2*1
  for 4 digit-> 5*4*3*2
  for 3 digit-> 5*4*3
  for 2 digit->5*4
  for 1 digit-> 5
  =120 + 120 + 60 + 20 +5
  => 325
