Question 1142641

lisa is five times older than her son. After 2 years, the sum of their ages will be 40, how old are they now?
<pre>Probably meant 5 times AS OLD, which is NOT the same as 5 TIMES OLDER. 
It'd be better for the problem to state that she is 5 TIMES HER SON'S AGE. Much easier, and PERFECTLY CORRECT.
