The ratio of females to males was 7 to 5

7x = # of females
5x = # of males

There were twice as many women as girls

To avoid working with fractions, revise our expressions for the numbers of females and males:
21x = # of females
15x = # of men

Again, there were twice as many women as girls:

14x = # of women
7x = # of girls

There were twice as many boys as men

10x = # of boys
5x = # of men

There were 68 more girls than men:

7x = 5x+68
2x = 68
x = 34

# of men: 5x = 170
# of women: 14x= 476
# of boys: 10x = 340
# of girls: 7x = 238

Total number of people: 36x = 1224

ANSWER: 1224
