If the digit h is the hundredths’ digit in the decimal number n = 0.3h7, what is the value of n rounded to the nearest tenth?

(1) n < 7/20: Say if n=0.347, then n=0.35 rounded off to 0.4. But if n=0.337, then n=0.34 rounded off to 0.3 Insufficient
(2) h < 5
. Use same example as above.

Can you please confirm this? I think answer should be E.

Hi..
If n=0.3h7 and you take h as 4, that is 0.347..
0.347 rounded to tenth will depend on just h , that is 4 and not 47
Ans will be 0.3 and not 0.4
You are first rounding to nearest hundredth and then that too nearest tenth, which is NOT correct.
Do the required action in the existing number directly.. so 0.347 means just 0.34 when you are rounding to tenths..

Great-Thanks for clearing my confusion. I am taking this as a rule since you are an expert I presume.
