Consider the following statements regarding the metrology and weight systems of the Indus Civilisation:
1. The Harappan weight system followed a dual pattern: binary in the lower denominations (1, 2, 4, 8, 16 to 64) and decimal in the higher denominations.
2. The standard cubic weights were manufactured primarily using polished grey flint and chert stone blocks.
Which of the statements given above is/are correct?

Question

Accepted Answer

Both statements are correct. Harappan commercial uniformity relied heavily on precise weights. Lower fragments used binary counting (where 16 was a core index ratio), while larger bulk trading entities scaled via decimal progressions (160, 320, 6400). Chert was the preferred stone due to its uniform density and resilience against scraping.
