Step-by-step explanation:

Given:-

the sum of two numbers is 15

and their HCF is 5

To find:-

find all such possible pairs numbers

Solution:-

Let the two numbers be X and Y

Their sum=15

=>X+Y=15_____(1)

Their HCF =5

The numbers be 5X and 5Y

Then (1) becomes 5X+5Y=15

If X=1 then Y=10

If y=1 then X=10

The possible pairs

(10,5);(5,10)

Answer:-

The possible pairs are (10,5) and (5,10)
