The correct option is 2 only
Explanation
The Harappan Civilisation developed a highly standardized and precise system of weights and measures to regulate commercial exchanges and trade across its vast territory. This uniformity is a hallmark of their urban planning and economic organization.
Statement-wise Analysis:
- Statement 1 is Incorrect: The weights used in the Harappan Civilisation were typically made of a stone called chert. They were generally cubical in shape and devoid of any markings. These weights were used for weighing jewelry, beads, and other commodities.
- Statement 2 is Correct: The system of weights was not purely decimal. The lower denominations of weights followed a binary system (1, 2, 4, 8, 16, 32, etc., up to 12,800). It was the higher denominations that followed the decimal system.
Key Takeaway:
Harappan weights were primarily made of chert and were cubical in shape. The weighing system utilized a binary progression for lower denominations and a decimal progression for higher denominations.
