How many 5 digits numbers can be formed using 1,2,3,4,5,6 which is divisible by 4 and repetition is not allowed.
1.96
2.144
3.192
4.216

• 3. 192
  for a no. to be divisible by 4, last 2 digit should be multiple of 4
  
  12,16,24,32,36,52,56,64
  last 2 places can be filled in 8 ways
  remaining three places can be filled in 4*3*2 = 24 ways
  
  total no. formed = 8*24 = 192

• last 2 places can be filled.........
  _ _ _ 1 2
  _ _ _ 1 6
  _ _ _ 2 4
  _ _ _ 3 2
  _ _ _ 3 6
  _ _ _ 5 2
  _ _ _ 5 6
  _ _ _ 6 4
  
  remaining 3 places can be filled.... 4*3*2 ways=24 ways
  
  total no.... 24*8=192

• for test the divisibility than find the combination and then use the permutation and combination and the answer is come down .
  12,16,24,32,36,52,56,64
