Trending @Cognizant; Query related to leave policy

Hi, I have a small doubt

If we work for 5 days in a week we are given 2 days weekoff

What if we take 7 days leave, Should we need to apply leaves for 7 days or only for the working days which we are missing?

This last week I have went for a vacation, Manager asked to join and work for 2 days in between,I was asked to apply leaves on weekoff day as well so the total timesheet hours are 54 hours including leaves,

Kindly shed some light on these policy
