Shalu is now two-thirds of Shaina's age.
In six years, Shalu will be four-fifths of Shaina's age.
In 15 years, Shalu will be seven-eighths as old as sister Shaina.
If they are both under the age of ten, how old are they now?
6 and 9 years old
In 6 years--------> x+6= 4/5*(y+6)
In 15 years --------> x+15= 7/8*(y+15)
x and y < 10
solving above we get x=6, y=9
