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 /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)
(20, 6, 4)
(24, 7, 5)
Answer & explanation
Correct answer: option 1
(20, 6, 4)
(24, 7, 5)
The logic followed here is :
(IInd number)2 - (IIIrd number)2 = Ist number
As
(6)2 - (4)2 = 20
(7)2 - (5)2 = 24
Similarly In option 1
(9)2 - (4)2 = 65
