Select the set in which the numbers are related in the same way as the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking them into their constituent digits. E.g. 13 – Operations on 13 such as adding/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations is not allowed.)
[4, 25, 6]
[3, 28, 9]

Correct option is A

Given: 

[4, 25, 6]
[3, 28, 9]

Logic: 1st × 3rd + 1 = 2nd 

Set I - [4, 25, 6] = 4 × 6 + 1 = 24 + 1 = 25​

Set II - [3, 28, 9] = 3 × 9 + 1 = 27 + 1 = 28 

Similarly, 

(a) (7, 22, 3) = 7 × 3 + 1 = 21 + 1 = 22

Correct answer is (a)
