$<b>The ratio is 7:8. Let the no. Of blue balls = 8x Number of red balls = 7x. Now, 3 red balls are taken out. So, red balls inside the bag is 7x - 3. 6 blue balls are added. So, blue balls inside the bag is 8x + 6. Now, the new ratio of red ball to blue ball is 3:5. So, (7x - 3)/(8x + 6) = 3/5. Cross multiplying gives 5(7x - 3) = 3(8x + 6) Or, 35x - 15 = 24x + 18 Or, 11x = 33. X = 3$

So, initial number of red balls = 7x = 21

Initial number of blue balls = 8x = 24.
