Given, Number of white balls = 20 Let x be the number of black balls. Total number of balls in the bag = 20 + x Also, the probability of drawing a black ball from the bag is 6.25 times that of drawing a white ball. ⇒ x/(20 + x) = 6.25[20/(20 + x)] ⇒ x = 125 Hence, the number of black balls in the bag = 125.
