Equal parts of 10 & 30 V. developer will yield 20 v.
Mixing 10 Volume developer and 40 volume developer will never make a 20 volume regardless of how much is mixed. In order to make a 20 volume, equal parts of 10 and 30 volumes will need to be mixed. Mixing 10 and 40 will make 30 volume.
To create a 30 volume cream developer, you will need to mix equal parts of 10 volume cream developer and 20 volume cream developer. Therefore, you mix 1 part 10 volume developer with 1 part 20 volume developer to achieve a 30 volume solution.
Equal parts of 10 & 30 V. developer will yield 20 v.

No, doubling the 20 volume creme developer will not give you the same results as using 40 volume creme developer. The strength of the developer impacts how much lift or color deposit it provides, so it's best to use the recommended developer for your desired outcome.
The typical ratio for mixing hair dye is 1:1, meaning equal parts of color cream dye and developer cream. The volume of the developer cream (measured in percentages like 10, 20, 30, 40 vol) does affect how much lift/lightening you will achieve. In general, the higher the volume of developer, the more lift you can expect, but it can also cause more damage to the hair.
