heya!
here is the solution to your question!
Let the age of grand be x
So, the equations formed = 10x ( i ) and 54 + x
ATQ
10 x = 54 + x
10 x - x = 54
9 x = 54
x = 54 / 9
x = 6 ( age of grand daughter )
Now, about the equation ( ii ) by which their present ages will be found.
=> 54 + x
=> 54 + 6
=> 60 years ( age of grand father )
