Solution

The correct option is A
3

Initially,

Number of red balls = 5
Number of blue balls = 4
Total number of balls = number of red balls + number of blue balls = 5 + 4 = 9

Now, after one blue ball is removed,
Number of blue balls = 3
Total number of balls = number of red balls + number of blue balls = 5 + 3 = 8

So, the correct answer is 3 and 8.
