ok i confused myself... i used 1/3 of 600 and added... so getting 800... o well.... it's late...
600 + 0.333x = x
600 = 0.666x
600/0.666 = x
x = 900
Very easy, but nice twist (I only knew because another teaser used the exact same twist, so I was ready this time).

What twist? 600 = 2/3, 3/3 = ? shouldn't take more than two seconds. Five if you're slow. Longer than that, you're overthinking it.
Of course, other teasers have house bricks, ducks, elephants or whatever rather than horses but how are all of these not duplicates of each other?
For example see Mad-Ade's other puzzle #2403 where it is a brick this time instead of a horse.
