Answer:

I. 3 green and 1 purple

II. 1 green and 3 purple

III. 3 green and 3 purple

All can be added

Step-by-step explanation:

Initial ratio is green : purple = 10 : 40

= 1 : 4

If we add more of green marbles and purple marbles to the initial one, there will definitely be an increase in the ratio

For instance,

I. 3 green and 1 purple

II. 1 green and 3 purple

III. 3 green and 3 purple

All of them will cause and increase in the ratio.
