I am 92 kgs , daily i JOG 4kms so how many days i take to become 75 kgs ?

You want to lose no more than .9 kgs a week to remain healthy, and in my opinion happy! If you increase your running and eat more healthfully, you can expect to reach your target weight in about 20 weeks or 5 months. I would allow yourself more freedom though and lose weight more slowly. Aim for a good six months of diet and exercise.
