<PRE><B>Question 1013902</B>
Call their ages NOW, b and s.  Thus we have
b = (5/6)s  or s = (6/5)b
In eight years she will be s + 8 and five years ago he was b - 5. So we have
s + 8 = 4(b - 5)
Substituting we get
(6/5)b + 8 = 4b - 20
Now subtract (6/5)b and add 20 to each side and get
(14/5)b = 28
Now multiply by 5/14 and
b = 10 so that
s = 12</PRE>
