In a zoo, 30% of the people are males. 50% of the remaining are females and the remaining 630 are children. Find the total number of people in a zoo.
Let the total number of people be x. Male = 30% of x = 3x/10 Remaining = x - 3x/10 = 7x/10 Female = 50% of (7x/10) = 7x/20 Now, children left = x - (3x/10 + 7x/20) = 630 => 7x/20 = 630 => x = 1800 Total number of people in a zoo is 1800.
