Let number of men in the population be x.
Number of women = (24000-x)
Increase in the number of men = 6% of x = 6x/100
Increase in the number of women = (3500-x)*9/100
Increase in whole population = 25620-24000 = 1620
Now, 6x/100 + [(24000-x)*9/100] = 1620
[(6x-9x)+24000*9]/100 = 1620
-3x+24000*9 = 1620*100
-3x = 162000-216000
X = 18000
Number of men = 18000
Number of women = 24000-18000 = 6000.
