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.)
(60, 15, 40)
(100, 50, 20)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (200, 40, 50).
Logic: (2nd number × 3rd number) ÷ 10 = 1st number
(60, 15, 40) ⇒ 15 × 40 = 600; 600 ÷ 10 = 60
(100, 50, 20) ⇒ 50 × 20 = 1000; 1000 ÷ 10 = 100
Similarly, (200, 40, 50) ⇒ 40 × 50 = 2000; 2000 ÷ 10 = 200
