my take is answer is E
let the digit be ***.****** or it is ********.*
stmt 1 ) says 10(***.******) tenth is 7 == ****.***7* or *******7*
so no conclusion
similarly statment 2 also is inconclusive
2) The thousandths digit of d/10 is 7.
says (***.******)/ thousandths digit is 7 == ***.**7*7* or *****7*7.*

Greatly appreciated....

If one is not comfortable with fonts and also does not wish to use X's, here is another way.
Let d= uvw.xyz
question: is y>5?
1) 10d = uvwx.yz and, therefore, tenths digit i.e. y=7, which is greater than 5.
2) d/10 = uv.wxyz hence thousandths digit i.e. y=7, which again is greater than 5.
Hence, D. Use of distinct alphabets may make it easier to understand (in my opinion). Hope this helps.
