Options:

649

658

650

648

Correct Answer:

648

Explanation:

The logic here is: x : x × (x - 3)

13 : 130 ⇒ 13 : 13 × (13 - 3) ⇒ 13 : 13 × 10 ⇒ 13 : 130

same as

15 : 180 ⇒ 15 : 15 × (15 - 3) ⇒ 15 : 15 × 12 ⇒ 15 : 180

Similarly ,

27 : ? ⇒ 27 : 27 × (27 - 3) ⇒ 27 : 27 × 24 ⇒  27 : 648

648 is correct answer .
