In a village, the population is not more than 6000.

If there are;
10% more boys than girls
15% more women than men
20% more children than adult
Find the number of boys girls,women and men?

b = 1.1 g

w = 1.15 m
b+g = 1.2( m+w)
b + g + w + m </= 6000
well to solve for exact numbers you need to say 6000, If we get fractional people we can truncate to whole people
1.1 g + g = 1.2 m +1.2*1.15 m
or 2.1 g = 2.58 m

1.1 g + g + 1.15 m + m = 6000
or 2.1 g + 2.15 m = 6000
so
2.5m +2.15 m = 6000
4.65 m = 6000
m = 1290.322581 men so 1290
