Question

A bag contains 5 red balls and 4 blue balls. If I take one blue ball out of the bag, the number of blue balls left and the total number of balls left will be ___ and ___ respectively.

• A. 3
• B. 8
• C. 5, 9
• D. 4, 8

Answer 1

The correct option is A

3

Initially,
Number of blue balls = 4
And, 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
And, total number of balls = Number of red balls + Number of blue balls = 5 + 3 = 8

So, the correct answer is 3 and 8
