Question 1149318
.
You can easily solve it MENTALLY in your head, without using equation/equations.


<pre>
(1)  In 9 years the sum of their ages will be 100 ---- hence, now the sum of their ages is  100-2*9 = 100-18 = 82.



(2)  Cary is 6 years older than Dan and the sum of their ages is 82.



     Take half of 82, which is 41, and <U>SUBTRACT</U> half of 6, i.e. 3, from 41 --- you will get  41-3 = 38 years.

     It is the age of the younger men, Dan.



     Take half of 82 again, which is 41, and <U>ADD</U> half of 6, i.e. 3, to it --- you will get  41+3 = 44 years.

     It is the age of the older men, Cary.
