Number of students applied in 2015 = 5,000 Number of students applied in 2016 = 1,500 Number of students applied in 2017 = 5,500 Total applications in 2015, 2016 and 2017 = 5,000 + 1500 + 5500 = 12,000 If each applicant has to submit Rs. 500 as application fees ∴ Total fees collect by the college in the last three years = 12,000 × 500 = 60,00,000
