Select the set in which the numbers are related in the same way as are the numbers of the following sets.
NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 -Operations on 13 such as adding deleting multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on I and 3 is not allowed)
(18, 27, 225)
(15, 33, 240)

(18, 27, 225)
(15, 33, 240)

Logic: Third Number = (1st Number + 2nd Number) $$\times$$ 5

Set (18, 27, 225)

225 = (18+27)×5

225 = 45×5

240 = (15+33)×5

240 = 48×5

Let's analyze the options:

(30, 15, 225):

225 = (30+15)×5

(22, 49, 568):

568 = (22+49)×5

568 =71×5

Logic is not matched.

(33, 38, 568):

568 = (33+38)×5

568 =71×5

Logic is not matched.

(25, 45, 560):

560 = (25+45)×5

560 =70×5

Logic is not matched.

Thus, the correct option is (a)
