Problem
The diagram shows part of a scale of a measuring device. The arrow indicates an approximate reading of
![[asy] draw((-3,0)..(0,3)..(3,0)); draw((-3.5,0)--(-2.5,0)); draw((0,2.5)--(0,3.5)); draw((2.5,0)--(3.5,0)); draw((1.8,1.8)--(2.5,2.5)); draw((-1.8,1.8)--(-2.5,2.5)); draw((0,0)--3*dir(120),EndArrow); label("$10$",(-2.6,0),E); label("$11$",(2.6,0),W); [/asy]](http://latex.artofproblemsolving.com/e/e/a/eea86891575ef6a6c7c90ff41c59a2a847689a3b.png)
Solution
Clearly the arrow marks a value between 
and 
, so only 
and 
are possible.
Looking, we see that the arrow is closer to 
, so
