Let the number of females of tribe Raba be x. Number of males of tribe Raba = 1.4x Total population = 4800 => x + 1.4x = 4800 => x = 2000 Number of males of tribe Raba = 1.4 × 2000 = 2800 Number of females of tribe Raba = 2000 Total population of tribe Dimasa = 4800 × 1.2 = 5760 Number of males of tribe Dimasa = (5/12) × 5760 = 2400 Number of females of tribe Dimasa = (7/12) × 5760 = 3360 Required ratio = 2000 : 3360 = 25:42
