On an average you need 30k exclusive rent If you can manage cooking cleaning I think you can go with it.
Don't forget salary does come along with deductions calculate wisely and make a decision

I'm near 25LPA, but my spend (including 2kg protein powder per month) comes within 30k - including rent. So yes

Depends on lifestyle and area where you will be staying. But I would say 8LPA is good enough though you might not able to save a lot
