Correct option is C
Given:
9 : 725
3 : 23
Logic: cube of the first number – 4
Check for 9 : 725
93=729
729 − 4 =725
729 − 4 =725
Check for 3 : 23
33=27
Now:
27 − 4 = 23
Now:
27 − 4 = 23
Now, check options:
(a) 8 : 315
83=512
512 − 4 = 508
(b) 5 : 128
53=125
125 − 4 = 121
(c) 4 : 60
43=64
64 − 4 = 60 (Follows)
(d) 6 : 220
63=216
216 − 4 = 212
Thus, correct option is (c).
