Blue balls	12	3	5
Green balls	11	6	9

How many fewer blue balls are there than green balls?

• A. 6
• B. 5
• C. 4
• D. 7

Answer 1

The correct option is A 6

Solution:
Let’s calculate the total number of red balls, the total number of blue balls, and the total number of green balls.

Types of balls	Store A	Store B	Store C	Total
Red balls	4	7	12	23
Blue balls	12	3	5	20
Green balls	11	6	9	26

So, the difference between the number of green balls and the number of blue balls $=26-20=6$
Thus, there are $6$ fewer blue balls than green balls.
