Ok, for this, lets try a chart seeing which two numbers add up to 31 up until the Brother (first number)is older than the Sister (2nd number) and see which one has the boy 5 years older than his sister.\r
\n" ); document.write( "\n" ); document.write( "0-31
\n" ); document.write( "1-30
\n" ); document.write( "2-29
\n" ); document.write( "3-28
\n" ); document.write( "4-27
\n" ); document.write( "5-26
\n" ); document.write( "6-25
\n" ); document.write( "7-24
\n" ); document.write( "8-23
\n" ); document.write( "9-22
\n" ); document.write( "10-21
\n" ); document.write( "11-20
\n" ); document.write( "12-19
\n" ); document.write( "13-18
\n" ); document.write( "14-17
\n" ); document.write( "15-16
\n" ); document.write( "16-15\r
\n" ); document.write( "\n" ); document.write( "Look closely and you'll see that 18 is 5 higher than 13. This means the boy is 18 and his sister is 13
\n" ); document.write( " \n" ); document.write( "
\n" );
