If the number of students passed in Business is increased by 30 and the number of students passed in Accounts is decreased by 30, then the number of students passed in Accounts is approximately what percent of the number of students passed in Business?

Business = 2400 × 25/100 = 600 After increasing 30 students = 600 + 30 = 630 Accounts = 2400 × 15/100 = 360 After decreasing 30 students = 360 – 30 = 330 Required percentage = 330/630 ×100 = 52.4% ≈ 52%
