If the average (arithmetic mean) of a, b, and c is (a+2b)/3, what is the value of b?
1) a=1
2) c=2
==> If you modify the original condition and the question and check the question again, from is (a+2b)/3=(a+b+c)/3, you get a+2b=a+b+c, then b=c. In order to find b, you only need to know c.
Therefore, the answer is B.
