***BOGO*** Select Query

Hi,
I wanted to know when doing a select query how is it executed :
If there is 1000 records with price<10, 3000 records with flag='Y' and the table contains 200,000 records.
Select code, description, price, flag from products where flag='Y' and price<10
Select code, description, price, flag from products where price<10 and flag='Y'
Which one of the query will be faster? In query 1, will mysql sort the list for flag='Y' then from the list find price<'10'?
Regards,
Velen
