a bag contains white,blue and red balls in the ratio 8:3:2. there are 10 red balls. If 10 white and 10 blue balls are removed from the bag, find the new ratio​

If you have 10 red balls, you have blue balls in proportion 3:2, so you have 15 blue balls. Moreover, you have white balls in proportion 8:2=4:1, so you have 40 white balls.Removing 10 white and blue balls causes you to have 30 white, 10 red and 5 blue balls.Since 30=5*6 and 10=5*2, the new proportion of white, red and blue balls is 6:2:1.
