He's A years old now.
4 years from now, he will be A+4.
10 years ago he was A - 10
------------
"thrice older" is 3 times older = 4 times as old.
1 time older = 100% older = 2 times as old
2 times older = 200% older = 3 times as old
3 times older = 300% older = 4 times as old
-------
A+4 = 4(A-10) = 4A - 40
3A = 44
A = 14 yrs, 8 months
-----------------------------
3 times older is not 3 times as old.
3 times more is not 3 times as much.
3 times farther is not 3 times as far.
3 times closer is nonsensical, since 1 time closer --> no distance.
3 times smaller is nonsensical, since 1 time smaller --> zero.
