Quipu were used by which civilization?

• A. Aztec.
• B. Maya.
• C. Inca.
• D. Olmec.

Answer: (C)

Quipu were a recording system used by the Inca to manage state data across a vast empire that didn’t rely on a traditional writing system for administration. Knotted cords and their arrangement encoded numbers and categories, allowing officials to track census figures, taxes, labor tribute, and inventories. The decimal setup and the way cords and knots were organized made it possible to carry and update complex information efficiently as administrators moved through the territories. Other civilizations, like the Maya, Aztec, and Olmec, used different writing or pictorial methods, so quipu are most closely associated with the Inca.
