\r
\n" ); document.write( "\n" ); document.write( "Let x games have to play.\r
\n" ); document.write( "\n" ); document.write( "total no. of games = x + 20 \r
\n" ); document.write( "\n" ); document.write( "no. of winning games = 15 + x/2 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "according to question,\r
\n" ); document.write( "\n" ); document.write( "15 + x/2 = 60 % of (x+20)\r
\n" ); document.write( "\n" ); document.write( "=> 15 + x/2 = (x+20) * 60/100\r
\n" ); document.write( "\n" ); document.write( "=> 15 + x/2 = 60x/100 + 12\r
\n" ); document.write( "\n" ); document.write( "=> 15 - 12 = 60x/100- x/2 \r
\n" ); document.write( "\n" ); document.write( "=> 3 = x/10\r
\n" ); document.write( "\n" ); document.write( "=> x = 30\r
\n" ); document.write( "\n" ); document.write( "so, total 30 games have to play.......\r
