Question
The ratio of males and females in a zoo is 5:6
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 4320 then what will be the total population in a zoo?Solution
Let the number of males and females be 5x and 6x respectively. Percentage of children among females = 20% So, 80% of females are adults, => 80/100 × 6x = 4320 => 6x = 5400 => x = 900 Total population = 5x + 6x = 11x = 11 × 900 = 9900
