A pile of balls consists of red and white balls. It is known that the number of white balls is less than the number of red balls, but twice the number of white balls is more than the number of red balls. If each white ball is marked with "2" and each red ball is marked with "3", the total sum of these balls is exactly "60". How many white balls are there?
