Select the option in which the numbers share the same relationship in set as that shared by the numbers in the given 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)
(39, 78, 81)
(42, 84, 87)
Answer & explanation
Correct answer: option 3
(39, 78, 81)
(42, 84, 87)
The logic followed here is :
(39) × 2 = 78 and 78 + 3 = 81
as
(42) × 2 = 84 and 84+ 3 = 87
Same as (84, 168, 171)
(84) × 2 = 168 and 168+ 3 = 171
