A father is 27 years older than his son. Ten years ago he was twice as old
as his son. How old is the father
~~~~~~~~~~~~~
It can be solved mentally.
Ten years ago the father was 27 years older than his son AND twice as old as the son.
Hence, ten years ago the son was 27 years old, while the father was 2*27 = 54 years old.
It means that NOW the father is 54 + 10 = 64 years old. ANSWER
