<PRE><B>Question 1059000</B>
 Bertha is three times as old as Martha but four times as old as Gifty. Find their respective ages if the sum of their ages is 84 years.
-----
Equations:
B = 3*M
B = 4*G
B + M + G = 84
-------------------------
B + (1/3)B + (1/4)B = 84
------------
12B + 4B + 3B = 12*84
--------------------------------
19B = 12*84
B = 53.05 years
----
M = (1/3)53.05 = 17.68 years
B = (1/4)53.05 = 13.26 years
