Raghu wants to draw water from the well. The minimum length of the rope that he can use is_____

Answer 1

As in the rainy season the water level 5 m above and the new level was 20-5=15m. wall of the well and pulley is (1.20+. 80)m= 2m. After water level rises 5 m above the previous level, water level is now (20 - 5) = 15 m below the ground level.
