If digit h is the hundredths' digit in the decimal d = 0.2h6, what is the value of d, rounded to the nearest tenth?

(1) d < 1/4

(2) h < 5

According to the ETS Official Guide, the answer to this question is that both (1) & (2) are sufficient. The Guide says that so long as you can tell whether h < 5 or h >= 5 you can solve the problem. Obviously, (1) & (2) enable us to tell that h < 5. However, I thought the answer is that neither are sufficient because if h = 4 then the 6 causes it to round up to 5 and therefore d = 0.3 when rounded to the nearest tenth. Am I missing something? Thanks in advance for your help.

[edited] yes, I agree with Dharmin. Let me try explain the confusion.

If I am corect, the confusion is around if h = 4.

d = 0.2h6

If h = 4, and you want to round to the nearest tenth, then d = 0.2. You don't first round the hundredth and then round the tenth - a sort of 'double rounding'.

(If h = 4, and you want to round to the nearest hundredth, then d = 0.25).

As far as the first condition, if d<.25, then it could be 0.24, 0.23, 0.22...and these rounded to the tenth, gets you d = 0.2

I hope that helps.

Correct yar, answer should be "Each statement is individually sufficient to answer the question"
If we construe "d, rounded to the nearest tenth" - meaning d = 0.2 , 0.3 , 0.4 , 0.5 ...
As we know, Rounding means adding up 1 if the next number is > 5.
Both choices say, h (which is next to 2) is < 5.
So in any case you need not to add 1 and thus you can easily say d = 0.2 after rounding it to nearest ten.

hope i am clear enough

I agree with Dan. No double rounding....
