Three baskets A, B and C contain different numbers of differently colored marbles. Basket A contains 4 red marbles and 2 yellow marbles. Basket B contains 6 green marbles and 1 yellow marble. Basket C contains 3 white marbles and 9 yellow marbles. What is the difference between the number of each color of marble in the basket that has the greatest difference? Let's answer step by step:
In basket A the number difference between differently colored marbles is 4 - 2 = 2. In basket B the difference is 6 - 1 = 5. In basket C the difference is 9 - 3 = 6. Comparing 2, 5 and 6 shows that 6 is the greatest difference. The answer: 6.
