Let’s trace Satish's steps:
Satish starts facing some direction.
He takes two right turns, and then one left turn.
Now, let’s see how he ends up facing south:
1. If Satish starts facing East:
The first right turn makes him face South.
The second right turn makes him face West.
The left turn makes him face South.
Since Satish ends up facing South after these turns, he must have started facing East.
So, Satish started from the East.
