male population is x
female population is 9600-x
108/100*x+105/100*(9600-x) = 10272
108x/100 +10080 - 105x/100=10272
3x/100=192
x=6400

Answer: 6400
Step-by-step explanation:
Current population= 10272
Population 1 year ago= 9600
Change in population = (10272-9600)= 672
Change in female = +5%
Change in male = +8%
% change in population = 672*100/9600 = 7%
8%. 5%
7%
2 : 1
No of male = 2/3*9600. = 64000
