Correct Answer - Option 1 : 56 : 136
The logic followed here is:
From option 1 -
136 - 56 = 80, It is not square of the number.
From option 2 -
89 - 25 = 64, It is square of the number 8.
From option 3 -
127 - 78 = 49, It is square of the number 7.
From option 4 -
97 - 61 = 36, It is square of the number 6.
Option 2, 3 and 4 are the square value but option 1 is not square value.
Option 1 is different from others.
Hence, "option 1" is the correct answer.
