Lets take 123x7 as an example for this problem, where x is the tens digit.

Statement 1 - When 123x7 is multiplied by 1000, we get 123x7000, where thousands digit is 7. Doesn't give any info about x. Therefore, NOT SUFFICIENT.

Statement 2 - When 123x7 is divided by 1000, we get 12.3x7, where hundredths digit is 7 => x = 7. SUFFICIENT.

Answer B.

Let the 5 digit integer be abcde. We need to find d.
1. abcde X 1000= abcde000, so the thoudsands digit of this number if e. Therefore we cannot find d from this information. Hence insufficient.
2. abcde/1000= ab.cde
here c is tenth digit and d is hundredth digit. Hence when given the hundredths digit we can say that d=7

hence sufficient.

Remember: tens digit is not same as tenths digit.

123.45: Here 2 is tens digit while 4 is tenths digit

Hence B.
