***
5 yrs ago:
let x=Sam's age
2x=Nina's age
..
At present:
x+5=Sam's age
2x+5=Nina's age
..
In 5 yrs:
x+5+5=x+10=Sam's age
2x+5+5=2x+10=Nina's age
2x+10=1.5(x+10) (In five years, Nina will be 1.5 times as old as Sam.
2x+10=1.5x+15
0.5x=5
x=10
..
x+5=15
2x+5=25
..
How old are Nina and Sam.
Nina: 25
Sam: 15
