Answer 2

The given question is 457=21

648=20

745=18

627=?

we have to find the similarities between the terms.

The above-given equivalents work in the concept or logic of.

The 648= 20 can be linked as

$648 = 20 \\ 6 + 4 + 8 = 18$

On adding 2 to the resultant value the answer is found true.

$4 + 6 + 8 = 18 \\ 18 + 2 = 20$

Hence obtained.

let's check the second option whether or has the same logic or different logic

$745 = 18 \\ 7 + 4 + 5 = 16 \\ 16 + 2 = 18$

Hence, this option also follows the same concept or logic.

Then for the first option, we can solve using the same concept but it doesn't follow the concept. The option must have the answer as

457=18

then the correct option for the given question is

$627 = x \\ 6 + 2 + 7 = 15 \\ 15 + 2 = 17$

the final answer is obtained as 17.

Hence, the final answer to the given question that follows a similar logic is 17.
