Target question :    What is the hundreds digit of integer n?

Statement 1 : The tens digit of n/10 is 4  
  Key concept: When a number is divided by 10, the hundreds digit of the original number becomes the tens digit of the new number.   
Example: When we divide 5  4  32 by 10, the resulting number is 5  4  3.2.
So, if the tens digit of n/10 is 4, then   4 is the hundreds digit of n  
Since we can answer the  target question  with certainty, statement 1 is SUFFICIENT

Statement 2 : The thousands digit of 10n is 4 
  Key concept: When a number is multiplied by 10, the hundreds digit of the original number becomes the thousands digit of the new number.   
Example: When we multiply 5  4  32 by 10, the resulting number is 5  4  320.
So, if the thousands digit of 10n is 4, then   4 is the hundreds digit of n  
Since we can answer the  target question  with certainty, statement 2 is SUFFICIENT

Answer: D
