\n" ); document.write( "My age was 1/3 of my fathers' age $\"highlight%28cross%28before%29%29\"$ 18 years ago. Now my fathers' age is twice as my age. What is my age now?
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For me, this formulation does not seem to be perfect. Much better is this:\r

\r\n" );
document.write( "     18 years ago, my age was 1/3 of my fathers' age. Now my fathers' age is twice as my age. What is my age now?\r\n" );
document.write( "

\r
\n" ); document.write( "\n" ); document.write( "The solution below corresponds to this formulation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Let M be my age now. \r\n" );
document.write( "Then my father's present age is 2M.\r\n" );
document.write( "\r\n" );
document.write( "18 years ago\r\n" );
document.write( "\r\n" );
document.write( "M - 18 = .\r\n" );
document.write( "\r\n" );
document.write( "To solve it, multiply both sides by 3. You will get\r\n" );
document.write( "\r\n" );
document.write( "3M - 54 = 2M - 18,\r\n" );
document.write( "\r\n" );
document.write( "3M - 2M = 54 - 18,\r\n" );
document.write( "\r\n" );
document.write( "M = 36.\r\n" );
document.write( "\r\n" );
document.write( "Answer. My present age is 36 years.\r\n" );
