Question

In Indus Valley Civilization (about $3000$ BC), the bricks used for construction work were having dimensions in the ratio

• A. $4:4:1$
• B. $4:2:1$
• C. $4:3:2$
• D. $1:3:4$

Answer 1

The correct option is B $4:2:1$

In Indus Valley Civilization, the bricks used for construction work were having, dimensions in the ratio $\text{length}:\text{breadth}:\text{thickness}=4:2:1$
Let us say, if $\text{thickness}=x$, then $\text{breadth = 2x}$ and $\text{length}=4x$.
Hence, option (b) is correct.
