the number of boys is exactly the number of girls,
and the number of boys and the number of girls should be whole numbers.
So, = number of girls, and
= number of boys,
must both be whole numbers.
So would be = number of children.
The ratio of children to adults is ,
so the ratio of adults to children is ,
and the total number of adults is
.
Among the adults (men and women),
the ratio of number of men to total number of adults is
, and
the ratio of number of women to total number of adults is
.
So,
the number of men is , and
the number of women is .
The number of women, men, and boys, respectively, are
, , and ,
and they must all be whole numbers,
which means that must be a multiple of
, , and .
The least common multiple is
.
The total population would be
.
With , the total population would be .
The next multiple of , ,
would make the total population .
So, the number of girls is .
The number of boys is .
The number of men is .
The number of women is .
