Answer:

A. 40 %

Step-by-step explanation:

Identify first how may marbles are red

200 (total number of marbles) - 120 (black marbles) = 80 (red marbles)

Afterwards, get the percentage of the red marbles...

80 ÷ 200 = 0.4

Don't forget to multiply it by 100 to get the percentage...

0.4 × 100 = 40

Therefore, the percentage of red marbles is 40 %
