In a company printing work is done by two machine 5% of the work done by machine A are wasted ,
\n" ); document.write( " and 40% of work done by machine B are wasted.
\n" ); document.write( " if the 80% of the total work is done by machine A. then what is the total percentage of wastage.
\n" ); document.write( ":
\n" ); document.write( "Let 1 = total amt done by both machines
\n" ); document.write( "Machine A does 80%
\n" ); document.write( "Machine B does 20%
\n" ); document.write( ":
\n" ); document.write( "Using decimals
\n" ); document.write( "Machine A wastes .05(.8) = .04 of total wasted
\n" ); document.write( "Machine B wastes .40(.2) = .08 of total wasted
\n" ); document.write( "---------------------------------
\n" ); document.write( "total from both machines: .12 * 100 = 12% wasted \n" ); document.write( "

\n" );
