  3. let d total amount b X litres...
    1st day: drink X/2...
    2nd day: X/4...
    3rd day: X/8.. n so on...
    so each day u drink half the amount u drank d previous day...

  4. a fantastic answer by Tarun

    Actually a general answer is just vary the quantity of the bottle in accordance with a decreasing function which has x = 0 as assypmtote
    and the difference between the values of y for consecutive integral value of x will give you the amount of your drink everyday

    so this decreasing geometric series is one of the answers
