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)
(17, 59, 625)
(8, 44, 784)
Answer & explanation
Correct answer: option 2
(17, 59, 625)
(8, 44, 784)
The logic followed here is :
IInd number - ( ist number× 2 ) = Square root of iiird number
As
59 - (17 × 2 ) = Square root of 625
59 - 34 = 25
25 = 25
and
44 - (8 × 2 ) = Square root of 784
44 - 16 = 784
28 = 28
Similarly (12, 69, 2025)
69 - (12 × 2 ) = Square root of 2025
69 - 24 = 45
45 = 45
