Stranded on a deserted island, Harry Puttar is left with only a 40 litres container of milk. To conserve his milk he decides that on the first day he will drink one litre of milk and then refill the container back up with water. On the 2nd day he will drink 2 litres and refill the container. On the 3rd day he will drink 3 litres and so on... By the time all the milk is gone, how much water has he drunk?
Answers
Answer:
It is given that the man has 40 litres container of milk.
Also, he will drink 1 litre on the first day, and refill the container with water, and will drink 2 litres on the second day.
He will refill the container, will drink 3 litres on the third day and refill the container again, and so on till the 40th of day.
Thus, at the end of 40 days, he must have drunk (1 + 2 + 3 + 4 + ..... + 38 + 39 + 40) = 820 litres of liquid.
Out of those 820 litres, 40 litres is the milk which he had initially.
Hence, he must have drunk 780 litres of water.
Answer:
780 litres
Step-by-step explanation:
ATQ
Harry drank some amount and then filled it with water
so, suppose he drank 1 litre of milk then filled the same amount with water
then the second day out of the 2 litres he drank 1 litre was previous day's water and the rest one litre was milk (basically n-1 amount was water), following this we get
1st day-0 litres water
2nd day - 1 litre water so on and so forth till forty
add the amounts which you get. finally you get 780
thank you!!!
