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 down the numbers into their 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)
(5, 9, 450) (7, 12, 840)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. (6, 9, 540).
The logic used here is:
(5, 9, 450)
5 × 9 = 45
45 × 10 = 450
(7, 12, 840)
7 × 12 = 84
84 × 10 = 840
Similarly,
(6, 9, 540)
6 × 9 = 54
54 × 10 = 540
Hence, (6, 9, 540) is the correct answer.
