Total no. is students appeared in the examination = 400
No. of girls who appeared in the examination and passed = 130
No. of boys who appeared in the examination = 400 - 130 = 270
No. of boys who passed in the examination = (2/3) × 270 = 2 × 90 = 180
Therefore, no. of boys who failed in the examination = 270 - 180 = 90.
