Correct Answer: 272


Solution : Given:
16 : 20 :: 256 : ? :: 49 : 56

In the above-given pairs, find the square root of the first number. Then, multiply the resultant with its successor to get the second number.
Like, 16 : 20→$\sqrt16$ = 4; (4 + 1) × 4 = 5 × 4 = 20
And, 49 : 56→$\sqrt49$ = 7; (7 + 1) × 7 = 8 × 7 = 56
Similarly, follow the same pattern for 256→$\sqrt256$ = 16; (16 + 1) × 16 = 17 × 16 = 272

So, 272 is related to 256. Hence, the fourth option is correct.
