Please add the Magento version in your question.

Also, check the contents of app/etc/applied.patches.list. If you have previously installed other patches, they will be listed there. And please read through the release notes for SUPEE-7405 v.1.1 as it clearly states that you will need to install SUPEE-7405 v.1.0 before installing the version 1.1.

What the log means is that while patching the file app/code/core/Mage/Adminhtml/Helper/Sales.php, it has found that the file has already been patched. Assume -R? [n] is asking you if you want to reverse the patch, which by default is set to [n]. Again, it is asking if the patch should be applied anyway (Apply anyway? [n]). And again it is set to No.

This means that the patch has already been applied to your site. To make sure of this, please check the app/etc/applied.patched.list file. Also, check the patch details if your version is affected by the patch or not. If you have the latest version, most probably, you will not need to apply the patch.
