• Divisible rule of 3 is that "add digit of number and divide the total sum by 3 and check it is divisible by 3 or not."
  
  
  2+3+4+5=14 which is not divisible by 3
  9+8+7+5=29 which is not divisible by 3
  6+5+0+4=15 which is divisible by 3
  9+8+3+3=25 which is not divisible by 3

• 3^1=3,3^2=9,3^3=27,3^4=81,3^5=243
  That means number with last digits 3,9,7,1 can be divisible by 3.
  9833 is the only number that is divisible by 3

• none is the answer because.......
  3^1=3
  3^2=9
  3^3=27
  3^4=81
  3^5=243
  3^6=729
  3^7=2187
  3^8=6561
  3^9=19683

• ans:none of these
  3^0=1
  3^1=3
  3^2=9
  3^3=27.......
  the unit digit for powers of 3 will be (1 or 3 or 9 or 7)
  and the power also divisible by 3.
  9833 has unit digit 3 but not divisible by 3
