Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.
6: 136 :: 8 : ? :: 12 : 568
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 248.
Logic : (First number × 2)2 - 8 = Second number
As,
6 ∶ 136 ⇒ (6 × 2)2 - 8 = (12)2 - 8 = 144 - 8 = 136
12 ∶ 568 ⇒ (12 × 2)2 - 8 = (24)2 - 8 = 576 - 8 = 568
Similarly,
8 ∶ ? ⇒ (8 × 2)2 - 8 = (16)2 - 8 = 256 - 8 = 248
Hence, the correct answer is 248.
