Question

In each of the following question, select the related number from the given alternatives.
$4$ $:$ $19$ $:$ $:$ $7$ $:$ $?$

• A. $49$
• B. $52$
• C. $28$
• D. $68$

Answer 1

The correct option is B $52$

The first two words are related such as $N^2+3$

Thus first pair is $\left[\right(4^2)+3=19]$.

The next pair that follows a similar analogy is $\left[\right(7^2)+3=52]$ as shown in option B.

Thus correct answer is $52$.
