Select the set in which the numbers are related in the same way as are the numbers of the given 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 /Subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed)

(14,378,9)
(18,432,8)

Correct option is B

Logic: 1st number × 3rd number × 3 = 2nd number

Given

Set 1. (14, 378, 9):

Apply the logic: 14 × 9 × 3 = 378

Set 2. (18, 432, 8):

Apply the logic: 18 × 8 × 3 = 432

This is correct.

Now, let's check the options:

Option A: (5, 125, 8)

Apply the logic: 5 × 8 × 3 = 120 ≠125

Option B: (15, 405, 9)

Apply the logic: 15 × 9 × 3 = 405 = 405

This matches the 2nd number.

Option C: (15, 305, 7)

Apply the logic: 15 × 7 × 3 = 315≠305

Option D: (11, 265, 8)

Apply the logic: 11 × 8 × 3 = 264≠265

The correct set is Option B (15, 405, 9)
