530000

Explanation:

When rounding, always START at the place you want to have the final digit. Then move to the right and look at that value. If it is 4 or less, leave the desired place digit as it is. If it is 5 or more, "round it up" to the next higher value.

In this case we want to end up with the 10-thousand place, which is the '3' in 531,000. So, we look to the right, and find a '1'. So, we just retain the '3' and drop the rest.

IF the next digit had been '6' for example - 536,000 - we would have rounded the '3' up to a '4' and obtained 540000 instead.
