• 1,2,3,4,5 its divisible by 4 means last 2 digit are divisible by 4
  means 12,24,32,52(4 possibility to divisible by 4)
  remaining 3 place can be filled in 3*2*1 ways for each.
  total 4 digit no. formed=4*3*2*1=24

• 5 digit no -----
  12,24,32 are divisible by 4,so last 2 blanks can be filled in 3 ways
  now there are 3 no and 3 blanks 1st blank can be filled in 3 ways repetition is not allowed so 2nd blank in 2 ways and 3rd in 1 way
  3*2*1*3=18 ways
