Q28: Consider the following statements regarding the standardized system of weights in the Harappan civilization:
1. The standard weights used for Harappan commercial exchanges were typically made of a distinct stone called chert and were generally cubical with no engraved markings.
2. The lower denominations of these weights strictly followed the decimal system, while the higher denominations followed a binary system.
3. Archaeologists have excavated actual metal scale pans at Harappan sites, indicating that these precise stone weights were used in conjunction with balancing scales.
Which of the above statements is/are correct?
2. The lower denominations of these weights strictly followed the decimal system, while the higher denominations followed a binary system.
3. Archaeologists have excavated actual metal scale pans at Harappan sites, indicating that these precise stone weights were used in conjunction with balancing scales.
Which of the above statements is/are correct?
✅ Correct Answer: B
🎯 Quick Answer:
Option B is the correct answer because statement 2 incorrectly reverses the mathematical systems used for the weight denominations.Structural Breakdown: The standard weights were manufactured from a hard stone known as chert.
They were strictly geometric (cubical) and completely devoid of script or decorative markings.
Physical metal scale pans have been found alongside them, proving their functional use in measuring goods.
Historical/Related Context: The precision of these weights was astonishing for the ancient world.
The smaller weights were likely used by specialized artisans for measuring high-value, lightweight luxury items such as gold, silver, and semi-precious beads.
Causal Reasoning: Statement 2 is false.
The system was structured so that the lower denominations followed a binary system (1, 2, 4, 8, 16, 32... up to 12800), which is ideal for simple halving and doubling of small quantities.
Conversely, the higher denominations utilized the decimal system, allowing for the calculation and transport of massive bulk agricultural goods.
