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.)
(27, 405, 3) (23, 690, 6)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (24, 600, 5).
Logic: (1st number × 3rd number) × 5 = 2nd number
(27, 405, 3) → (27 × 3) × 5 = 81 × 5 = 405
(23, 690, 6) → (23 × 6) × 5 = 138 × 5 = 690
Similarly, (24, 600, 5) → (24 × 5) × 5 = 120 × 5 = 600
