The ratio of males and females in a city is 7 : 8 and the percentage of children among males and females is 25% and 20% respectively. If the number of adult females in the city is 156800 what is the total population?
Options:
(A) 245000
(B) 367500
(C) 196000
(D) 171500
(E) None of these Hmmm, my stream of consciousness:
Number of females = 156800 10080 = 196000
\ Number of males = 78 196000 = 171500
\ Total population = 196000 + 171500 = 367500 So, the answer is (B).
