Select the option in which the numbers shares the same relationship in set as that shared by the numbers in the given 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)
(8, 63, 81)
(11, 120, 144)
Answer & explanation
Correct answer: option 1
(8, 63, 81)
(11, 120, 144)
The logic followed here is :
(Ist number)2 - 1 = second number and (Ist number + 1)2 = Third number
as
(8)2 - 1 = 63 and (8 + 1)2 = 81
(11)2 - 1 = 120 and (11 + 1)2 = 144
same as (9, 80, 100)
(9)2 - 1 = 80 and (9+ 1)2 = 100
