Perhaps you used the wrong -p or --strip option? The text leading up to this was:

Answer 1

1) Compare this file app/code/core/Mage/Sales/Model/Quote/Item.php is differ from the core file. download Magento 1.9.3.2 and check any changes in this file.

2) We understand the meaning of Hunk #1 succeeded at 350 (offset 1 line). if the file to be patched has changed slightly or any space since the patch was created, but the specific section remained the same, patch can detect that and apply the patch appropriately.

That means the file was successfully patched, but the first section that was patched was 350 lines earlier than was originally specified.

It is same for Hunk #{number} succeeded items
