Correct Answer: 504


Solution : Given:
15 : 270 :: 21 : ? :: 18 : 378

Like, 15 : 270→(15) 2 + (15 × 3) = 225 + 45 = 270
18 : 378→(18) 2 + (18 × 3) = 324 + 54 = 378
Similarly, follow the same pattern for 21 : ?→(21) 2 + (21 × 3) = 441 + 63 = 504

So, 504 is related to 21. Hence, the second option is correct.
