My answers don't make sense, but I'll tell you what I got
Let M = my age in 2003
Let G = grandpa's age in 2003
G+=+11M given
Nine years lat in 2012,
I am M+%2B+9 years old
My grandpa is 11M+%2B+9 years old
also given, in 2012 grandpa's age is 3%28M+%2B+9%29
Therfore, 11M+%2B+9+=+3%28M+%2B+9%29
11M+%2B+9+=+3M+%2B+27
8M+=+18
M+=+2.25 or 2y 3m old in 2003
And grandpa's age in 2003 was
G+=+11M
G+=+11%2A2.25
G+=+24.75 or 24y 9m old in 2003
This is too young to be my grandpa. How old could he have been
when my father was born? If I made a mistake, I don't see it.
