Games played=7
\n" ); document.write( "Games won=4
\n" ); document.write( "

\n" ); document.write( "No of games in season=16
\n" ); document.write( "Required record=60%
\n" ); document.write( "They need to win a certain number of games out of 16 to get a 60% record.
\n" ); document.write( "Let this certain number be x
\n" ); document.write( "Then we get,
\n" ); document.write( "(x/16)*100=60
\n" ); document.write( "x/16=60/100
\n" ); document.write( "x=(60/100)*16
\n" ); document.write( "x=(6/10)*16
\n" ); document.write( "x=9.6
\n" ); document.write( "Which becomes 10 when rounded off
\n" ); document.write( "Therefore to get a 60% minimum,they need to win 10 games out of 16.
\n" ); document.write( "

\n" ); document.write( "Then number of games in season=16
\n" ); document.write( "Number of games they need to win=10
\n" ); document.write( "But we know that,
\n" ); document.write( "No of games already played=7
\n" ); document.write( "No of games already won=4
\n" ); document.write( "So we are left with,
\n" ); document.write( "No of games left to play=16-7=9
\n" ); document.write( "No of games left to win=10-4=6
\n" ); document.write( "

\n" ); document.write( "So out of their remaining 9 games they need to win 6 to get a season record of 60%
\n" ); document.write( "
