The sum of two numbers is 40 and their difference is 4. The ratio of the numbers is:
Answer: 11:9
Explanation
Let the two numbers be x and y, where x>y.
We are given:
x+y=40(1)x−y=4(2)
Adding equations (1) and (2):
2x=44⟹x=22
Subtracting equation (2) from (1)
2y=36⟹y=18
The numbers are 22 and 18.
The ratio of the numbers is:
x/y=22/18
=11/9
