The correct option is B 147.35
It is given that the total marks is 600 and David scored 452.65.
So, to find out how much marks he lost, we just need to subtract his marks from the total.
First 600 has to be rewritten in such a way that it also has 2 decimal places, that is, 600 = 600.00
Now let's subtract,
600.00−452.65=147.35
