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.)
(10, 450, 5) (8, 360, 5)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (7, 189, 3)
The logic used here is:
(10, 450, 5) = 10 × 5 = 50, 50 × 9 = 450
(8, 360, 5) = 8 × 5 = 40, 40 × 9 = 360
Similarly,
(7, 189, 3) = 7 × 3 = 21, 21 × 9 = 189
