A Bag contains \(a\) white and \(b\) black balls.

Two players A And B. Alternately draw a ball from the bag replacing the ball each time after the draw till one of them draws a white ball and wins the game.

It is given that A begins the game.

Also, it is given that the ratio of winning probabilities of A And B is 3.

Then find the nearest integer to 150(a/b).
