P + M = 126
P = 2 ( M - (P-M) )

Let GrandPa = GP
And GrandMa = GM
GP is twice older than GM = 2(GM)
GP is twice older then GM was when GP was as old as GM is now = 2(GM-(GP-GM))

By Solving the equations, we get
GP present Old = 72yrs
GM present Old = 54yrs

Now, Difference of GP and GM age is = 72-54 = 18yrs

So, When GM was 18(Diff of present age), GP age was Twice as GM = 2(18) = 36yrs

Satisfies all the Condition.
