Question

In mathematics, the number $\varphi$ is an irrational number that is roughly equal to $1.618$... Which letter corresponds to the correct placement of $\varphi$ on the number line below?

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is B B

Since the part between $1$ and $2$ is divided into $10$ parts , so, each part measures $0.1$.

$\varphi =1.618$ is to be located on the number line.

$1.6<1.618<1.7$

So, on analysis, we can say that point B is the correct point.
