Let x the first number, y the second number.
equation 1: x/y = 4
equation 2: x+y =20
equation 3: manipulate equation 1 ----> x=4y
substitute equation 3 to equation 2:
4y+y=20
5y=20
y=20/5
y=4
solve for the value of x by substituting the value of y to equations 1 or 2:
using equation 1:
x/4=4
x=4*4
x=16
using equation 2:
x+4=20
x=20-4
x=16
Therefore, the two (2) numbers are: 4 and 16.

The quotient of two and the sum of a number and twenty
The numbers are: 80 and 4
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
The sum is the result you get when you add two or more numbers together. A single number can be the sum of two or more other numbers when they are added together but cannot be expressed as you ask in your question. Though you could ask "What numbers have the sum of 20?" For instance 20 is the sum of (10 + 10), (5 + 15), (2 + 7 + 11) etc., but is not in itself a sum.

The quotient of two and the sum of a number and twenty
The numbers are: 80 and 4
15 and 5
(x + y)/20
A quotient is when two numbers are divided. For instance 20 ÷ 5 = 4 in this case, the quotient is 4.
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
The sum of two numbers is those two numbers multiplied together. For instance, the sum of 4 and 5 is 20.
The quotient is the result of dividing two numbers. So if you need to find the quotient of 20 and 5, you would divide 20 by 5. That means that your answer (4) would be the quotient.
