In a learning experiment at Stanford University it was found that the square of the inverse of learning time varies directly as the age of a rat in weeks, while the inverse of learning time and complexity index of the maze are directly related. If the age of the rat in standing trial of the experiment is 40% more than in the first trial and the learning time is 16.67% less, then find change in complexity index of the maze.
