Question
In a zoo, 25% of the people are males. 40% of the
remaining are females and the remaining 720 are children’s. Find the total number of people in a zoo.Solution
Let the total number of people be x. Male = 25% of x = x/4 Remaining = x - x/4 = 3x/4 Female = 40% of (3x/4) = 3x/10 Now, children left = x - (x/4 + 3x/10) = 720 => 9x/20 = 720 => x = 720 x (20/9) => x = 1600 Total number of people in a zoo is 1600.
