Answer:

B (2 violet)

Explanation:

Let the colors be represented by their first letter. Then the balances give rise to two equation:

o +y +b +v = r +g +b

o +y +v = g +v

Subtracting the second equation from the first gives ...

(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)

b = r +b -v

Adding v-b to both sides, we have ...

b +(v -b) = r +b -v +(v -b)

v = r

Multiplying this result by 2, we can match the final balance:

2r = 2v . . . . . . . choice B
