A total of 155500 students were enrolled from April 2005 to July 2005. What percent of students enrolled in a year, from April 2005 to march 2006, actually enrolled in the first quarter of the year?
22%
The number of enrolments in the first quarter (April 2005 to June 2005) = 155500 – (7.68% of 527000) = 115000. Thus the required percentage = (115/527)*100 = 22%.
