What is the ratio of b to c?
(1) b is 2 more than half of c.
(2) 2b/5c = 1/2
According to the OE, in (1), we cannot convert that equation in a ratio, because the left side of the equation has two terms. Could someone please explain this? How can we be sure that this equation cannot be converted in a ratio?
OA: B

OA: B
b = 2 + c/2.
If c=2, then b = 2 + 2/2 = 3, with the result that b/c = 3/2.
If c=4, then b = 2 + 4/2 = 4, with the result that b/c = 4/4 = 1.
Since b/c can be different values, INSUFFICIENT.
Statement 2: 2b/5c = 1/2
(2/5)(b/c) = 1/2
b/c = (5/2)(1/2) = 5/4.
SUFFICIENT.
The correct answer is B.
