A bag contains 12 balls out of which `x` are white. If one ball is drawn at random, what is the probability that it will be a white ball? If 6 more white balls are put in the bag, the probability of drawing a white ball will be double than that in (i). Find `x` .

A bag contains 20 balls out of which x balls are white.If one ball is drawn at random,the probability drawing a white ball is y.Now place this ball and 10 more white balls in the bag.Now if a ball is drawn from the bag,the probability of drawing the white ball is 2y. Find x.
