          The question is correct and the answer to the question is - 438. Know how it is -

          Ans:Solution -

          C D E A B C
          18 : 19 : 20 8 : 9 : 10
          x 5 x 5 x 5 x 9 x 9 x 9
          90 95 100 72 81 90

          Her total score = 72 + 81 + 90 + 95 + 100 = 438. The question can be solved faster using ratio approach.
