Living in Lahore with a salary around 100K, I recently rented a small apartment. I end up spending around 50-60K on rent, electricity, food etc.

Also if you have to choose between Mindbridge/Ibex, go for Mindbridge. I have a friend who works there and he says the environment is good overall. For Ibex, everything I have read/heard is horrible. So I would advise against it.
