(E)0.497 mark = 1$.

1 mark = \(\frac{1}{0.497}\) $.

Let's round off 0.497 to 0.5.

1 mark = \(\frac{1}{0.5}\) $.

350 mark =\(\frac{350}{0.5}\) $ = 700 $

Now we are left with option D and E.

0.5 > 0.497

We know that dividing by a bigger number gives a smaller result. Since we divided by bigger of the two numbers ( 0.5 and 0.497 ), we got a smaller result.

Dividing with 0.497 ( the smaller number), as in the original equation would have given us a result bigger than 700.

The only option bigger than 700 is

E -> 704
