(1) The hundredths digit of x is 5 (2) Number x, rounded to the nearest tenth, is 54.5 Obviously (1) alone is not enough, so is BCE What is about information (2) rounded to the nearest tenth, is 54,5 So the number no rounded is 54,49X where X integer > 4 or 54,50X where X integer <5 So the the tenth digit can be 4 or 5, the information (2) alone is not enough to answer to this question. However since in the 1st information the undredths digit of x is 5, so the tenth digit is 4 Therefore the correct answer is C

Need a quick clarification on this. (I guess I don't need a clarification anymore, just thought i'd add the note below) What is Number x, rounded to the nearest tenth here? if x = 54.550000 ~ 54.6 if x = 54.458000 ~ 54.5 I guess I figured it out as I was typing this itself. Note: When the digit 5, 6, 7, 8, or 9 appears in the ones place, round up; when the digit 0, 1, 2, 3, or 4 appears in the ones place, round down

(1) The hundredths digit of x is 5 (2) Number x, rounded to the nearest tenth, is 54.5 is this question asking about tenth digit or decimal point? i think it should be tenth decimal point, and after rounding off it comes as 54.5 hence tenth decimal 0.5 remained as it is as hundredth digit was less than or equal to 5, e.g number was 54.55, I round it off , it becomes 54.5, if the number was 54.56, i round it off it becomes 54.6 if you dont consider first statement then there are two possibilities 54.47 will also become 54.5 and 54.52 will also become 54.5 hence we need both statements Hope i m making sense

(1) The hundredths digit of x is 5 (2) Number x, rounded to the nearest tenth, is 54.5 we have to find tenths digit of a number x (1) hundredths digit 0f x is 5 we can not find tenths digit from it, hence insufficient(2) Number x, rounded to the nearest tenth, is 54.5[/quote] here, we have two cases, if no is 54.50 to 54.54 then tenths digit is 5and if no is 54.45 to 54.49 then tenths digit is 4therefore (2) alone is not sufficientusing (1) and (2) together we clearly have no as 54.45, giving us tenths digit as 4 both statements together gives a unique answerAnswer CKudos, if you like the explanation

Hi All, In this prompt, we're asked for the TENTHS digit of X? This question asks for the digit that is to the IMMEDIATE RIGHT of the decimal point. Fact 1: The hundredths digit of X is 5 This tells us NOTHING about the tenths digit  that digit could be any integer from 0 to 9, inclusive. eg. X = _.05 X = _.15 X = _.25 ... X = _.95 Fact 1 is INSUFFICIENT Fact 2: Number X, rounded to the nearest tenth, is 54.5 This Fact discusses ROUNDING. If the hundredths digit is 04, then we 'round down'; if the hundredths digit is 59, then we 'round up.' eg. IF..... X = 54.49, then we would 'round up' to 54.5 X = 54.53, then we would 'round down' to 54.5 Thus, the tenths digit could be 4 or 5. Fact 2 is INSUFFICIENT Combined, we know... The hundredths digit of X is 5 Number X, rounded to the nearest tenth, is 54.5 Since the hundredths digit is 5, that means that we would have to round UP to get to 54.5. Thus, X could only be 54.45 Combined, SUFFICIENT Final Answer: GMAT assassins aren't born, they're made, Rich

the key point here is 'number x'.
As it is mentioned that it is a number and not an integer you can assume x = 0.abc and I guess rest of the problem can be referred from any of the well explained answers above.
