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 /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)
(36, 6, 18)
(35, 5, 21)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (49, 7,21).
Here the logic is : Third Number = (First Number ÷ Second Number ) x 3
⇒(36, 6, 18)
36 ÷ 6 x 3 = 6 x 3 = 18
⇒(35, 5, 21)
35 ÷ 5 x 3 = 7 x 3 = 21
Similarly,
(49, 7, 21)
49 ÷ 7 x 3 = 7 x 3 = 21
Hence, (49, 7, 21) is the correct answer.
