Reputation suddenly reduced: got no reason

I had a reputation of 126. However, it got reduced to 124 due to a negative vote on an answer.

Now I see it has become 116, though I could find no negative vote in my activity page.

Can the moderators, or the ones with greater reputation take a look and explain how this happened?

Help is greatly appreciated.

• So, how much does the reputation come down for that? Apr 3, 2017 at 13:36
• Offtopic suggestion: all capital nicks can look often not the best, please consider switching to simply "Wrichik Basu". Apr 4, 2017 at 19:21

You deleted one of your questions, which has $2$ upvotes and $1$ downvote, thereby removing $2\times 5+1\times(-2)=8$ reputation pts.
