Here's a little known but very useful factoid:
If they're inversely proportional,
then their product is constant.
Here's how to use it:
-- We're told that Y = 8 when X = 7.
So when y=8 and x=7, their product is 56 .
-- If Y REALLY varies inversely as X, then
their product is ALWAYS going to be 56.
-- So when Y=4, X= (56/4) = 14 .
The values of x and y are 15 and 75, respectively
<h3>How to determine the values of x and y?</h3>
The statements are given as:
- Angle x and angle y are complementary angles
- Angle y is 5 times the size of angle x
These mean that
x + y = 90
y = 5x
Substitute y = 5x in x + y = 90
x + 5x = 90
Evaluate the sum
6x = 90
Divide by 6
x = 15
Substitute x = 15 in y = 5x
y = 5 *15
Evaluate
y = 75
Hence, the values of x and y are 15 and 75, respectively

Answer:
Divide 120 by 100 (Because 120 is 100% of the animals). You get 1.2. Multiply 20% by 1.2 and get 24.
