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)

(4, 9, 16)

(25, 36, 49)

(49, 64, 81)

(4, 9, 16)

(25, 36, 49)

The logic followed here is :

Numbers are consecutive in order

1)  ( First number) ² , (Second number) ²   , (Third number )²

      4 ,  9 , 16

      2²  ,    3²  ,  4²

2) ( First number) ² , (Second number) ²   , (Third number )²

   25 ,  36 ,  49

  5²  ,  6²  ,  7²

Similarly IN option 1

( First number) ² , (Second number) ²   , (Third number )²

49 ,  64 , 91

7² , 8² ,  9²
