<PRE><B>Question 1194528</B>
The question is:
A man is currently six times older than his granddaughter. Thirteen years ago, he was 18 times older than her. What are their current ages?
-------------
Ignoring the fact that 6 times older = 7 times as old, and 18 times older is 19 times as old:
=====
M = 6G
M-13 = 18*(G-13)
---
6G-13 = 18G - 234
12G = 221 **** not integers
=============
M = 7G
M-13 = 19*(G-13)
7G-13 = 19G - 247
12G = 234
G = 19.5  **** not integers
-----------------------------
Age problems usually accept only integers.</PRE>
