Answer 2

Among the options 44-31 is the odd one

Given,

25-21,44-31,34-30,61-12

To Find,

Find out the odd one among 25-21,44-31,34-30,61-12

Solution,

• According to the Question, the first choice is 25-21.

So if we are substituting these two numbers 25 and 21, then the result is 4 and we all know that,

4= 2².

• Then the next numbers are 44-31. If we are applying the same method in this case also then you can find that 44-31= 13

13 is not square to any number

• The third one is 34-30. Applying the same logic we find the result of their difference is 4.

And, 4= 2²

• and at the last, the option is 61-12. If you are find their difference then you are finding that the difference between them is 49.

and, 49= 7²

so, Except 44 - 31, the difference of the remaining pairs are perfect squares.

Hence, 44-31 is the odd one
