Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 24 : 142.
Here the pattern followed is,
Option 2) 14 : 49 ⇒ 14 : 14/2 ⇒ 14 : (7)2 ⇒ 14 : 49.
Option 3) 16 : 64 ⇒ 16 : 16/2 ⇒ 16 : (8)2 ⇒ 16 : 64
Option 4) 34 : 289 ⇒ 34 : 34/2 ⇒ 34 : (17)2 ⇒ 34 : 289
Option 1) 24 : 142 ⇒ 24 : 24/2 ⇒ 24 : (12)2 ⇒ 24 : 144 ≠ 142
Hence, 24:142 is different from the rest.
