\n" ); document.write( "The difference in their ages will always be 2 years.

\n" ); document.write( "If the sum of their ages 3 years ago was 48, the sum of their ages now is 48+2(3) = 54.

\n" ); document.write( "If the sum of their ages is 54 and the boy is 2 years younger than his sister, simple logical reasoning tells us the boy is 26 and his sister is 28.
