Correct option is D
Given :
14 : 205
14² + 9 = 196 + 9 = 205
14² + 9 = 196 + 9 = 205
5 : 34
5² + 9 = 25 + 9 = 34
5² + 9 = 25 + 9 = 34
Logic: (number² + 9) = 2nd
A) 25 : 636
25² + 9 = 625 + 9 = 634 ≠ 636
25² + 9 = 625 + 9 = 634 ≠ 636
B) 16 : 247
16² + 9 = 256 + 9 = 265 ≠ 247
16² + 9 = 256 + 9 = 265 ≠ 247
C) 9 : 91
9² + 9 = 81 + 9 = 90 ≠ 91
9² + 9 = 81 + 9 = 90 ≠ 91
D) 28 : 793
28² + 9 = 784 + 9 = 793
28² + 9 = 784 + 9 = 793
Thus, correct option is (d).
