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.
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
