2. Direction (1-4): Study the data given below and answer the following questions Data is provided for 3 months for a water tank whose capacity is 60ooo0 L to provide continuous water supply to a building. Water tank is first completely filled and then it gets completely emptied to supply water in a building. It supply water continuously to the building and is refilled again and again to provide continuous supply. In the building there are 40 flats in which all flats may or may not be completely occupied in the given three months.
