3.2xy6
If x and y each represent single digits in the decimal above, what digit does x represent?
(1) When the decimal is rounded to the nearest tenth, 3.2 is the result.
(2) When the decimal is rounded to the nearest hundredth, 3.24 is the result
Obviously I can't get the answer from (1) alone.
From (2):
The number has to be 3.23y6 right? for y GE 4 (GE means Greater than or Equal to - Somehow the post gets mangled up if I use inequality symbol).
So we know the value of x is 3. So answer should be B. But it isn't.
Calista.
