I have double the age you had when I had the age you have. When you have my age, I will be 50 years old. When you were born, how old was I?

Your age is double mine. When my age is twice the age I have now you will be 50.

M0 = my age at birth (0)
X0 = your age at my birth

Mp = my age when you were my age
Xp = your age when you were my age (22)

Mn = my age at present (22)
Xn = your age at present = 2*Mp

We know that D = X - M is always constant no matter our ages, so we have:

D = Xp - Mp = 22 - Mp
D = Xn - Mn = 2*Mp - 22

Thus, 22 - Mp = 2*Mp - 22 and we have Mp = 44/3 = 14.66 ? 15

D ? 22 - 15 = 7 = X0

Generalized: D = Mn - 2*Mn/3
Where Mn is your age.

That means that my age will be equal to your age but is not now? Then you are a vampire born on a leap year?

Using this same encoding scheme we have:

D = X0
D = Mn - Mp
D = 2*Mp - Mn
D = 50 - 2*Mp

The number of equations exceeds the number of unknowns so is there is no solution.

Almost forgot, congratulations

It's weird how you people that solve the questions never post your solutions.
