document.write( "The ratio of children to women is  \"9%2F10\".\r\n" );

document.write( "\r\n" );
document.write( "The ratio of men to women is  \"4%2F5\" = \"8%2F10\".\r\n" );

document.write( "In other words, for each 10 women, there are 9 men and 8 children.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, we can group all the people in the train in groups consisted of 10 women, 9 men and 8 children each.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Every such group consists of 10+9+8 = 27 persons,\r\n" );
document.write( "so the number of groups is  \"270%2F27\" = 10.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  There are 10*10= 100 women,  9*10 = 90 men and  8*10 = 80 children in the train.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  100 + 90 + 80 = 270.    ! Correct !\r\n" );
