27

Suppose number is xy Then 3(x+y)=xy x=3y(3y-3) only for y=2 x is a interger So , the value of x is 2 Then pair the 2 with different value of y and it satisfies for 7 so the final pair is 27 Answer is 27

3(x+y)=xy

x=3y(3y-3)

only for y=2 x is a interger So , the value of x is 2

Then pair the 2 with different value of y and it satisfies for 7

so the final pair is 27
