Answer:
17 m
Step-by-step explanation:
Water in well = 20 m above the ground level
Water collected after rain = 5 m
Total water in well after rain = 15 m above ground level
Height of wall = 1 m 20 cm
Height of pulley = 80 cm above compound wall
Height of pulley above the ground level = 1 m 20 cm + 80 cm
= 2 m
Minimum length of rope required = 15 m + 2 m
= 17 m
