8 : 128 :: 6 : ? :: 11 : 242
Option 1: 64
Option 2: 72
Option 3: 68
Option 4: 70
Correct Answer: 72
Solution :
Given:
8 : 128 :: 6 : ? :: 11 : 242
Here, the pattern followed is as follows –
8 : 128→(8)² × 2 = 64 × 2 = 128
11 : 242→(11)² × 2 = 121 × 2 = 242
Similarly, follow the same pattern for 6 : ?→(6)² × 2 = 36 × 2 = 72
So, 72 is related to 6 in the same way as the second number is related to the first number and the sixth number is related to the fifth number. Hence, the second option is correct.
