You are 35 years old and will retire at 65. Currently, you have ₹100,000 with you and your aunt has promised to give you another ₹100,000 in her will. She is currently 70 years old. You have looked up the mortality tables applicable and, accordingly, expect her to live for another 10 years.

You expect to live for 20 years after your retirement. In accordance with your lifestyle and expected inflation, you wish to have ₹800,000 every year post-retirement. How much should you save every year from the end of the current year till retirement in order to have the desired sum post-retirement?

Your aunt actually expires in five years but has willed you ₹200,000 (bless her soul!). How much do you need to save for the balance period in order to have the same amount as you had originally planned every year after retirement?
