I believe the answer is D. This is because a HTU chart would show that the second 2 is in the tenths column.
HTU.THT
832 .248
This means that we need to pay attention to the 2 and that this should only go to one decimal place.
8 rounds up, so we add one onto the 4 to make 5. We now have 832.25
5 rounds up so we add one onto the 2 to make 3. We now have 832.3
We only need it to one DP so this is the answer.
(I think this is right, it's been a long time since I have been oing things at this level. I feel old. I hope this helped!)
