Question

A bag contains 5 red balls and 4 blue balls. If one blue ball is taken 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 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.
