<PRE><B>Question 106660</B>
Ricardo is 4 years less than twice as old as his sister.  The sum of their ages is 20.  How old is Ricardo?

----------------
NOW DATA:
Let his sister&#39;s age be &quot;x&quot;; Ricardo is &quot;2x-4&quot;
-------------------
EQUATION:
x + 2x-4 = 20
3x = 24
x = 8 (His sister&#39;s age)
2x-4 = 16-4 = 12 (Ricardo&#39;s age)
