Question

In the question, the numbers in the figure are related. Identify their relationship and find the missing number in the given figure.

• A. $6$
• B. $9$
• C. $10$
• D. $11$

Answer 1

The correct option is D $11$

Take the number from top of the triangle first than left one, and after than right one to form a three digit number.

Now, find its square root and divide it by two.

You will get the number at middle.
For example:
We get numbers $196,256$ and $484$ respectively.
Now $\frac{\sqrt{196}}{2}=7,\frac{\sqrt{256}}{2}=8,\Rightarrow \frac{\sqrt{484}}{2}=11$

Hence, option D.
