      C 410 Correct Answer Incorrect Answer
      D 420 Correct Answer Incorrect Answer

      Solution

      Number of boys in the college = 1800 X 0.60 = 1080 Number of girls in the college = 1800 - 1080 = 720 Number of boys who are enrolled in NSS = 1080 X 0.20 = 216 Number of girls who are enrolled in NSS = 720 X 0.25 = 180 So, total number of students who are enrolled in NSS = 216 + 180 = 396
