Question :

what is the following set of numbers is analogous to the given set of numbers ?

21:462::?​

Options:

30:931

23:552

17:296

13:142

Step-by-step explanation:

Given:

Set of numbers = $21:462$

To find:

Set of analogous numbers

Solution:

• The given set of numbers can be analysed as follows:

                             $462$ can be written as $(21\times21)+21$

                              i.e. $462=21^{2} + 21$

        Then given set of numbers can be written in the equation form as,                                                                          

                                   $x:x^{2} +x$

• The given options are validated against the above derived equation.
• $23:552$  ⇒    $552$  is written as $552=23^{2} +23$ which is analogous to the form $x:x^{2} +x$.
• Other options does not match with derived equation.

Hence, option $23:552$  is correct
