মনে করি, মোট = x ∴ Male = 3x/8 তাহলে, Female = (x-3x)/8 = 5x/8 rejected applicants = (3/4)× x =3x/4 rejected male applicants = (2/3) × (3x/8) =x/4 rejected female applicants = (3x/4) - (x/4) =(3x-x)/4 =2x/4 =x/2 after first round remaining male = (3x/8) - (x/4) =x/8 after first round remaining female = 5x/8-x/2 =x/8 Total = (x/8)+(x/8) = 2x/8 = x/4 male remains from total remaining is = (x/8)/(x/4) = x/8 × 4/x = 1/2Related questions
