Select the option in which the numbers are related in the same way as are the numbers of the following set.
(15, 7, 252)
Answer & explanation
Correct answer: option 1
(15, 7, 252)
The logic followed here is :
(Ist number)2 + (IInd number)2 - (ist number+IInd number) = IIIrd number
As
(15)2 + (7)2 - (15 + 7)
225 + 49 - 22 = 252
Same as
In (12, 16, 372)
(12)2 + (16)2 - (12 + 16) = IIIrd number
144 + 256 - 28 = 372
