Reasoning and answer: Jamie had two times more blue balls than red ones, so he had 2 blue / red * 16 red balls = 32 blue balls. He lost 6 red balls so he had only 16 red balls - 6 red balls = 10 red balls. In total he had 32 blue balls + 10 red balls = 42 red and blue balls. He bought 74 balls - 42 red and blue balls = 32 yellow balls.
The answer: 32
