I need info about double battle EVs?

Question

If I faint the opposing two Pokemon simultaneously with one of my Pokemon, willl my Pokemon gain EVS for both the Pokemon it fainted?
For example if my swampert uses earthquake and faints the opposing magneton and exploud at the same time, will it gain 3 HP EVs and 2 SP ATK EVs or will it only gain EVs from one of them?

Answer 1

It will gain EVs from both of the Pokémon it KO'ed. However, remember if this is competitively, i.e. your Pokémon don't gain experience, then they will not gain any experience.
