Let the faculties be X and the number of students be Y. X/Y = 17/3 3X= 17Y X=17Y/3 Let that be equation 1 We also know that X+Y = 740. Let it be equation 2 Substitute equation 1 in equation 2 (17Y/3)+Y= 740 20Y/3 = 740 Y=111 Since the total is 740, then X equal 740-111 =629. The number of faculties is 111 and the number of students is 629.
