Does the value of x remain unchanged when rounded to the tenths place?
To determine the answer we need to know the digit in hundredths place.
{Say X = 35.44. Then value of X rounded to the tenths place remains same (i.e., X = 35.4) and
say X = 35.46 then value of X rounded to the tenths place becomes X = 35.5}
(1) The value of x remains unchanged when rounded to the hundredths place.
this implies that the digit in thousandths place is below 5.
But it is not sufficient to answer the above question.
St1 is not sufficient
(2) The value of x remains unchanged when rounded to the units place.
this implies that the digit in the tenths place is below 5.
Again this information is not sufficient to answer the above question.
statement 1 and 2 together
Still we can't say anything about the digit in hundredths place
So Answer E

I think you are missing a point here. For example, The value of x remains unchanged when rounded to the hundredths place means that the hundredths digit is the rightmost nonzero digit of x. So, taking this into the account what would be the answer ?
