    HI          I ANSWERED THIS QUESTION YESTERDAY


    IF YOU HAVE  $10000 AT 12% FOR ONE YEAR THE INTEREST WOULD BE   10000 X 12/100 =


    120000/100 =  $1200


    AS THE TOTAL INTEREST REQUIRED IS $2200 SUBTRACT THE  $1200 ALREADY EARNT  THAT MEANS YOU REQUIRE  $1000 FROM THE REMAINING  $5000


       LETS CALL INTEREST    M        THEREFORE   5000 X M/100 = 1000         M/100 =1000/5000


    M/100 =1/5    THEREFORE       M = 100/5       M = 20%


    THEREFORE    $5000 AT  20% FOR ONE YEAR YEILDS  $1000 ADD THIS TO YOUR $1200 AND YOU HAVE YOUR TOTAL


    I HOPE YOU HAVE FOLLOWED THE WORKING OUT OF THIS PROBLEM IF NOT PLEASE POST ANOTHER QUESTION
