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 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.)
(45, 15, 3)
(120, 40, 8)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (165, 55, 11).
Logic: 3rd number × 5 = 2nd number; 2nd number × 3 = 1st number.
(45, 15, 3) → 3 × 5 = 15; 15 × 3 = 45
(120, 40, 8) → 8 × 5 = 40; 40 × 3 = 120
Similarly, (165, 55, 11) → 11 × 5 = 55; 55 × 3 = 165
