Question

In each of the following questions, select the related number from the given alternatives.
$37$ $:$ $23$ $:$ $:$ $19$ $:$ $?$

• A. $9$
• B. $5$
• C. $6$
• D. $8$

Answer 1

The correct option is B $5$

The first two words are related such as $37-x=23$

Thus $x=37-23\Rightarrow x=14$

The next pair that follows a similar analogy is $19-14=5$ as shown in option B.

Thus correct answer is $5$.
