An unpolarized light beam is incident on the polarizer of a polarization experiment and the intensity of light beam emerging from the analyzer is measured as $\displaystyle 100$ Lumens. Now, if the analyzer is rotated around the horizontal axis (direction of light) by $\displaystyle 30$° in clockwise direction, the intensity of emerging light will be \_\_\_\_ Lumens.
