Question
The ratio of males and females in a zoo is 4:5
respectively and the percentage of children among males and the percentage of children among females are 15% and 20% respectively. If the number of adult females in the zoo is 5200 then what will be the total population in a zoo?Solution
Let the number of males and females be 4x and 5x respectively. Percentage of children among females = 20% So, 80% of females are adults, => 80/100 × 5x = 5200 => 5x = 6500 => x = 1300 Total population = 4x + 5x = 9x = 9 × 1300 = 11700
