my mother recently done blood test and found that she is diabetic with 266 blood sugar level.Is there any chance of its reverse to normal blood sugar with proper medication

Ans: Diabetes can be managed with lowering blood sugar levels by following a healthy lifestyle and dietary modifications. Increasing basal metabolic rate by adapting to a high complex carbohydrate and fiber rich diet, with good protein foods and low total and healthy fats will ensure less spikes in blood sugar levels. Exercises which include building muscle mass and lowering body fat will lower the incidence of hyperglycemia. Avoid processed, canned foods, sweets, alcohol, fatty foods, etc. As the blood sugar levels are lowered, medication doses may need to be altered.

Ans: Yes, with appropriate diet and lifestyle changes.

Ans: The blood sugar levels and how tight control should be done is also influenced by age.
Her fasting blood sugar levels are acceptable. Post meal (2 hrs after the meal) can be in range of 70 to 180 mg%. Therefore, she is doing largely fine on that also. You can reduce post meal sugar level by some dietary modifications and cutting down on sugary and carbohydrate meals. Also, adding salads and fibers would also help.
It would be helpful to get to know her HbA1c levels so, I would get a sense of her overall sugar control.
