Call the two loans L1 and L2. with L1 > L2
\n" ); document.write( "Then, L1 - L2 = 10,000
\n" ); document.write( "commom interest rate = 5%
\n" ); document.write( "I1 = interest on L1
\n" ); document.write( "I2 = interest on L2
\n" ); document.write( "I1 = %5*L1 = 0.05L1
\n" ); document.write( "I2 = %5*L2 = 0.05L2
\n" ); document.write( "I1 + I2 = 2000
\n" ); document.write( ".: 0.05L1 + 0.05L2 = 2000
\n" ); document.write( "0.05(L1 + L2) = 2000
\n" ); document.write( "dividing both sides by 0.05
\n" ); document.write( "L1 + L2 = 40,000 ----------------(1)
\n" ); document.write( "but
\n" ); document.write( "L1 - L2 = 10,000 ----------------(2)
\n" ); document.write( "adding (1) and (2),
\n" ); document.write( "2L1 = 50,000
\n" ); document.write( "L1 = 25,000
\n" ); document.write( "===========
\n" ); document.write( "L2 = 15,000
\n" ); document.write( "===========
\n" ); document.write( "
\n" );
