  • Options
  • A. 4,12,480
  • B. 3,67,500
  • C. 5,44,700
  • D. 2,98,948

  • Correct Answer
  • 3,67,500 

    Explanation

    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
