document.write( "7 years ago, the sum of their ages was  114 - 2*7 = 100 years, and Sergio was 4 times Adriana's age.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, 7 years ago Adriana was 100:5 = 20 years and Sergio was 4*20 = 80 years old.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, now Adriana is 20+7 = 27 years old;  Sergio is 80+7 = 87 years old.    ANSWER\r\n" );
