Answer 1

Let the total population be 'p'
Given ratio of male and female in a city is 7 : 8
In that percentage of children among male and female is 25% and 20%
=> Adults male and female % = 75% & 80%
But given adult females is = 156800
=> 80%(8p/15) = 156800
=> 80 x 8p/15 x 100 = 156800
=> p = 156800 x 15 x 100/80 x 8
=> p = 367500
Therefore, the total population of the city = p = 367500
