Logic: ((First number ÷ 2) + 1)2 = Second number
1) 24 : 169 → ((24 ÷ 2) + 1)2 = (12 + 1)2 = 132 = 169
2) 12 : 49 → ((12 ÷ 2) + 1)2 = (6 + 1)2 = 72 = 49
3) 48 : 625 → ((48 ÷ 2) + 1)2 = (24 + 1)2 = 252 = 625
4) 36 : 365 → ((36 ÷ 2) + 1)2 = (18 + 1)2 = 192 = 361
∴ Here, '36 : 365' is different from other three alternatives.
Hence, the correct answer is "36 : 365".
