Can any one please explain the variation of intensity of a particular point on the screen of YDSE with changing the position of the source?

the intensities of the light(i1 & I2) from the slits is inversionally proportional to the square of the distance between the slit and the primary source of the light. then the ratio of the intensities of the maxima to minima = (root I1+ root I2)^2 / ( root I1- root I2)^2.
That is as the source is brought closer to the slit the intensity of the maxima increases. Threr wont be any change in the fringe width.
