The three people start with a total age of
\n" ); document.write( " $\"12+%2B+56+%2B+60+=+128\"$ so some years down the road their total age will go above 150. How may years fro now is that?
\n" ); document.write( "Let's assume that that happens in x years.
\n" ); document.write( "At that time, the three people will be
\n" ); document.write( "{{12+x}}}, $\"56%2Bx\"$ and $\"60%2Bx\"$ years old
\n" ); document.write( " $\"12%2Bx+%2B+56%2Bx+%2B+60%2Bx+=+150\"$
\n" ); document.write( " $\"128+%2B+3x+=+150\"$
\n" ); document.write( " $\"3x+=+22\"$
\n" ); document.write( " $\"x=7.333\"$
\n" ); document.write( "So in 7 years they will total to 149. in 7 years, they are 19, 63 and 67\r
\n" ); document.write( "\n" ); document.write( "At that point, whichever person has the earliest birthday will put them over the top (assumes that 2 or kmore of them are not born on the same day).
\n" ); document.write( "That makes three possible answers
\n" ); document.write( "(20, 63, 67) , (19,64,67) or (19,63,68)
\n" ); document.write( " \n" ); document.write( "

\n" );
