To find :-

What are the numbers ?

Solution :-

Given that

The ratio of two numbers = 2:5

Let they be 2X and 5X

Their difference = 5X-2X = 3X

According to the given problem

They differ by 18

=> 3X = 18

=> X = 18/3

=>X = 6

Now, 2X = 2×6 = 12

and 5X = 5×6 = 30

Answer:-

The two required numbers are 12 and 30

Check:-

The two numbers are 12 and 30

Their ratio = 12:30

=> 12/30

=> (2×6)/(5×6)

=> 2/5

=> 2:5

and

Their difference = 30-12 = 18

Verified the given relations in the given problem.
