\r\n" );
document.write( "From the condition, the father is 36-12 = 24 years older than Jodi.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, when the father age will be 24*2 = 48,  he will be twice Jodi's age.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It will happen in  48-36 = 12 years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  In 12 years father will be  36+12 = 48 years old;  Jodi will be 12+12 = 24 years old.\r\n" );
document.write( "\r\n" );
document.write( "            = 2.   ! Correct !\r\n" );
