Two coherent monochromatic light beams of intensities 4 I and 9 I interfere in a Young's double slit experimental setup to produce a fringe pattern on the screen. The phase difference between the beams at two points P and Q on the screen are / 2 and / 3 respectively. Then the ratio of the two intensities I_P / I_Q is
