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 1 and 3 is not allowed.)
(16, 20, 80)
(12, 16, 64)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (18, 22, 88).
Logic: 1st number + 4 = 2nd number; 2nd number × 4 = 3rd number.
(16, 20, 80) ⇒ 16 + 4 = 20; 20 × 4 = 80
(12, 16, 64) ⇒ 12 + 4 = 16; 16 × 4 = 64
Similarly, (18, 22, 88) ⇒ 18 + 4 = 22; 22 × 4 = 88
