Question
Two numbers are in the ratio 5:3. If they differ by 18, what are the numbers?
Solution
Let the common ratio between these numbers be x. Therefore, the numbers will be 5x and 3x respectively.
Difference between these numbers = 18
5x − 3x = 18
2x = 18
Dividing both sides by 2
`(2x)/2 = 18/2`
x = 9
First number = 5x = 5 × 9 = 45
Second number = 3x = 3 × 9 = 27
