(462/500)(225) = 207.9 were correct
---
225-207.9 = 17 were wrong

It doesn't say if all answers are weighted the same or not.
There a couple ways to look at this
225-462*225/500=17.1 so it might be 17 wrong and 218 right
but it could also be 18 wrong and 217 right since both answers are decimals.
It depends on which one you try to solve for for first.
