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 /deleting /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)
(21, 3 , 15)
(49, 7, 35)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (84, 12, 60).
Logic: Second number × 5 = Third number and Second number × 7 = First number.
As, (21, 3 , 15)
3 × 5 = 15
3 × 7 = 21
And, (49, 7, 35)
7 × 5 =35
7 × 7 = 49
Similarly, (84, 12,60)
12 × 5 = 60
12 × 7 = 84.
