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.
25 : 264 :: 31 : ? :: 49 : 456

25 : 264

49 : 456

31 : ?

Logic: First number × 8 + 8² = Second number

25 × 8 + 64 = 200 + 64 = 264

49 × 8 + 64 = 392 + 64 = 456

Similarly,

31 × 8 + 64 = 248 + 64 = 312

Thus, correct option is (a).
