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/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.)
(18, 3, 9)
(36, 6, 18)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (78, 13, 39).
Logic: 2nd number × 3 = 3rd number; 1st number ÷ 2 = 3rd number
(18, 3, 9) ⇒ 3 × 3 = 9; 18 ÷ 2 = 9;
(36, 6, 18) ⇒ 6 × 3 = 18; 36 ÷ 2 = 18;
Similarly, (78, 13, 39) ⇒ 13 × 3 = 39; 78 ÷ 2 = 39;
