Select the set in which the numbers are related in the same way as are the numbers of the followingsets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent
digits. E.g. 13 – Operations on 13 such as adding /subtracting /multiplying to 13 can be performed. Breaking down 13 into
1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(7, 11, 33)
(14, 18, 54)

Correct option is D

Given - (7, 11, 33)
(14, 18, 54)

Logic
Second = First + 4
Third = Second × 3
Let's confirm this with all valid sets:
Given Sets:
(7, 11, 33)
7 + 4 = 11 
11 × 3 = 33 
(14, 18, 54)
14 + 4 = 18 
18 × 3 = 54 
Option D: (12, 16, 48)
12 + 4 = 16 
16 × 3 = 48 
So, Option D is the only one that fully fits both conditions.
Final Answer: D) (12, 16, 48)

checking other options
A: (5, 9, 36)
9 × 3 = 27 ≠ 36 → wrong
B: (16, 20, 40)
20 × 3 = 60 ≠ 40 → wrong 
C: (18, 21, 63)
18 + 4 = 22 ≠ 21 → wrong
