I was wondering because EA refused to give sales numbers for that. They tend to do when a game sells well. It wasn't in the top 10 for UK or NPD charts in the first month that it was released.
They've said Inquisition had the best launch of any BW title in terms of sales and that it exceeded their expectations. Plus, look at the games released that month that made the top ten:
Call of Duty: Advanced Warfare (360, XBO, PS4, PS3, PC)
Grand Theft Auto V (PS4, XBO, 360, PS3)
Super Smash Bros. (Wii U, 3DS)
Madden NFL 15 (360, XBO, PS4, PS3)
Assassins Creed Unity (PS4, XBO, PC)
Far Cry 4 (PS4, XBO, 360, PS3, PC)
Pokemon Alpha Sapphire (3DS)
Pokemon Omega Ruby (3DS)
NBA 2K15 (PS4, 360, XBO, PS3, PC)
Halo: The Master Chief Collection (XBO)
Other than maybe Far Cry, I wouldn't have expected a Dragon Age game to outsell any of those.
