Select the number-cluster that is related to the third letter-cluster in the same way the first letter-cluster and fifth letter-cluster are related to the second number-cluster and sixth number-cluster. DRAGON: 210 :: BLAZER: ? :: EXPERT: 360

The logic followed here is: The product of the place values of the last two letters from the left end as per the English alphabetical series of the given word is the number-cluster. In 'DRAGON': The place values of the last two letters (O and N) are '15' and '14'. 15 × 14 = 210. So, 'DRAGON' is related to '210'. In 'EXPERT': The place values of the last two letters are '18' and '20'. 18×20=360. So, 'EXPERT' is related to '360'. Similarly, in 'BLAZER': The place values of the last two letters (E and R) are '5' and '18'. 5 × 18 = 90. So, 'BLAZER' is related to '90'.
