\n" ); document.write( "\n" ); document.write( "let 15% punch required be x\r
\n" ); document.write( "\n" ); document.write( "then 8% punch will be 14-x\r
\n" ); document.write( "\n" ); document.write( "15% ------------------ 8% -----------------10%\r
\n" ); document.write( "\n" ); document.write( "x-------------------==== 14-x-------------- 14\r
\n" ); document.write( "\n" ); document.write( "0.15x+0.08(14-x)=0.1*14\r
\n" ); document.write( "\n" ); document.write( "0.15x+1.12 - 0.08x = 1.4\r
\n" ); document.write( "\n" ); document.write( "0.07x= 1.4- 1.12\r
\n" ); document.write( "\n" ); document.write( "0.07x= 0.28
\n" ); document.write( "x=0.28/0.07\r
\n" ); document.write( "\n" ); document.write( "x=4\r
