Mutual fund I 4.00% per annum ------------- Amount invested =x

\n" ); document.write( " 3000
\n" ); document.write( "Interest----- 98
\n" ); document.write( "
\n" ); document.write( "Mutual fund I 4.00% per annum ---x
\n" ); document.write( "Mutual fund II 2.00% per annum ---y
\n" ); document.write( "Credit on both cards
\n" ); document.write( "x + 1 y= 3000 -------------1
\n" ); document.write( "Interestto be paid on both
\n" ); document.write( "4.00% x + 2.00% y= 98
\n" ); document.write( "Multiply by 100
\n" ); document.write( "4 x + 2 y= 9800.00 --------2
\n" ); document.write( "Multiply (1) by -4
\n" ); document.write( "we get
\n" ); document.write( "-4 x -4 y= -12000.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -2 y= -2200
\n" ); document.write( "divide by -2
\n" ); document.write( " y = 1100
\n" ); document.write( "Mutual fund I 4.00% $ 1900
\n" ); document.write( "Mutual fund II 2.00% $ 1100
\n" ); document.write( "
\n" ); document.write( "CHECK
\n" ); document.write( "1900 --------- 4.00% ------- 76.00
\n" ); document.write( "1100 ------------- 2.00% ------- 22.00
