Answer:
Option D can be the answer.
Step-by-step explanation:
A bag has more green balls than blue balls, and there is at least one blue ball. We can say that -
b is greater than or equal to 1
and g is always greater than b.
With respect too g, we can say b is:
g-1 or g-2, or generally g-n.
The equation thus becomes: 2(g-n) = g-n + g
which is equal to: 2g - 2n = 2g - n.
From this equation we can conclude that the left side is always smaller than the right side so:
2g - 2n < 2g - n.
Which becomes: 2b < g + b.
Hence, option D can be the answer.
