We have 4000 dollars of 2% investment.
\n" ); document.write( "Using the method of alligation.\r
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "2         2        4000 dollars of 2% investment\r\n" );
document.write( "      3            6000 dollars of 3% investment\r\n" );
document.write( "5         1 1/2*4000=2000 dollars of 5% investment\r\n" );
document.write( "           3\r\n" );
document.write( "

\n" ); document.write( "1= 3 - 2
\n" ); document.write( "2= 5 - 3
\n" ); document.write( "2000= 4000/(2/1) dollars of 5% investment to add to your 4000 dollars of 2% investment.
\n" ); document.write( "6000= (4000+2000) dollars of the final 3% investment.
\n" ); document.write( "check
\n" ); document.write( "0.05 * 2000 + 0.02 * 4000 = 0.03*(4000+2000)
\n" ); document.write( "100.0 + 80.0 = 0.03*(6000)
\n" ); document.write( "180.0 = 180.0
\n" ); document.write( "ok
\n" ); document.write( "
\n" );
