Trending @Infosys; How does wfo attendance work in infy?

Hi guys, I heard that in infy we need to be in 4.5 hrs at least to get the attendance marked. And for rest of the hrs of that we have to apply wfh. My query is if we used all 10 wfh of a month and on 11th day we are going to office and they applying remaining hrs as wfh,then that wfh will go as exception right to the supervisor, so will they approve it?
