Bricks used in Harappan houses were made in which fixed ratio of length, breadth and thickness?
- A.1:2:4
- B.2:2:1
- C.4:2:1
- D.3:2:1
Show answer
Correct answer: C. 4:2:1
Explanation
The correct answer is C, 4:2:1. A Harappan burnt brick was four units long, two units broad and one unit thick, and the same proportion turns up at sites hundreds of kilometres apart. This standardisation is one of the strongest arguments for a common authority or at least a shared set of rules across the civilisation, and it goes with the standard system of weights that runs in multiples of sixteen.
Option A, 1:2:4, is the same three numbers written backwards and is the commonest trap in this question; length is the largest of the three, so the ratio must begin with 4. Options B and D, 2:2:1 and 3:2:1, are simply wrong proportions and do not match any Harappan brick. Read the order of the words in the question stem carefully before choosing.
