Let
\n" ); document.write( "Total Rs. 10 = x notes
\n" ); document.write( "Total Rs. 20 =50-x
\n" ); document.write( "Total Number of Notes = 50
\n" ); document.write( "Total sum of all notes = 800\r
\n" ); document.write( "\n" ); document.write( "(10)(x)+(50-x)(20)=800
\n" ); document.write( "10x+1000-20x=800
\n" ); document.write( "-10x=800-1000
\n" ); document.write( "-10x=-200
\n" ); document.write( "Divide by -10
\n" ); document.write( "-10x/-10=-200/10
\n" ); document.write( "x=20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Total Rs. 10 = x = 20 notes
\n" ); document.write( "Total Rs. 20 =50-x = 50-20 = 30 notes\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
