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.)
(12, 8, 20)
(7, 3, 15)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (9, 4, 19).
Logic: First number × 3 - Second number × 2 = Third Number
(12, 8, 20) → 12 × 3 - 8 × 2 = 36 - 16 = 20
(7, 3, 15) → 7 × 3 - 3 × 2 = 21 - 6 = 15
Similarly, (9, 4, 19) → 9 × 3 - 4 × 2 = 27 - 8 = 19
