Question
The ratio of males and females in a zoo is 6:7
respectively and the percentage of children among males and the percentage of children among females are 15% and 25% respectively. If the number of adult females in the zoo is 4725 then what will be the total population in a zoo?Solution
Let the number of males and females be 6x and 7x respectively. Percentage of children among females = 25% So, 75% of females are adults, => 75/100 × 7x = 4725 => 7x = 6300 => x = 900 Total population = 6x + 7x = 13x = 13 × 900 = 11700
