Question

two numbers are in the ratio 5:3 if the differ by 18 what is the number

Answer 1

Let two numbers are 5x and 3x

If their difference is 18

5x-3x=18

2x=18

x=18/2

x=9

Then, numbers are 5*9=45

And

3*9=27

Answer 2

Let the ratio be 5x and 3x
Difference between them=18
Means
5x-3x=18
So
2x=18
x=18/2
x=9

Then the no. are
5x
5×9=45
And
3x
3×9=27
On proving
45-27=18
