Select the set in which the numbers are related in the same way as are the numbers of the following set.
(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, 81, 123)
(56, 32, 8)
Answer & explanation
Correct answer: option 1
(39, 81, 123)
(56, 32, 8)
The logic followed here is :
Ist number+ 42 = second number and second number + 42 = Third number
as
39 + 42 = 81 and 81 +42 = 123
Ist number - 24 = second number and second number -24 = Third number
as
56 -24 = 32 and 32 - 24 = 8
Same in option 1 (61, 57, 53)
Ist number - 4 = second number and second number - 4= Third number
61 - 4 = 57 and 57 - 4 = 53
