Question 1144493

<pre>
My three daughters are born 2 years apart and have a combined age of 63. How old is the eldest? 

--------

There are several ways to interpret this question, but I will use the interpretation that each daughter is born two years after the previously born daughter.  ("My three daughters were EACH born 2 years apart, and have a combined age of 63." )

With this interpretation, their ages are x, x+2, and x+4:

x + (x+2) + (x+4) = 63

3x + 6 = 63
3x = 57
x = 19  --> x+2 = 21  and x+4 = 23

The daughters are 19, 21, and 23.  The eldest is {{{ highlight( 23 ) }}} years old


I think the presentation of this question could be better.
