Option 1: 356
Option 2: 316
Option 3: 242
Option 4: 213
Correct Answer: 213

Given:
4 : 61 :: 9 : 726 :: 6 : ?
Subtract 3 from the cube of the first number to get the second number.
Like, 4 : 61→(4
3
– 3) = 64 – 3 = 61
And, 9 : 726→(9
3
– 3) = 729 – 3 = 726
Similarly, follow the same pattern for 6→(6
3
– 3) = 216 – 3 = 213
So, 213 is related to 6. Hence, the fourth option is correct.
