Given that Joseph has 24 cousins, and he has 6 more females than males, the number of females will be obtained as follows; suppose he had x males, number of females will be x+6. The total will be: x+(x+6)=24 x+x+6=24 2x+6=24 2x=24-6 2x=18 x=18/2 x=9 thus the number of male cousins is 9, the number of female cousins will be 9+6=15 We therefore conclude that he has 9 male cousins and 15 female cousins
