What is my Reputation Score?

It's the sum of all votes (up and down) you have ever got. 🤓

According to https://hiveblocks.com/@goel.tarun your rep is 60.8 - or:

9,516,361,861,410
I believe this is all r-shares summed up, but not sure.
The other number is logarithmified.

Perhaps one front-end has some author info cached? Or it's rounded up?
Maybe refreshing helps.
It's a bit glitched, I guess.

At the end of the day, your reputation does not really matter unless it's negative;
That's the only reason that number was introduced in the first place.
