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.)
(2, 3, 36)
(1, 7, 49)

Logic: Square of 1st × Square of 2nd = 3rd Number.
$$(2,3,36) = (2^2×3^2= 36) \ \ \\(1,7,49) = (1^2× 7^2 = 49)$$​​
Now Similarly ,
​$$(4,4,252)= (4^2 × 4^2= 256) \\ \ \\(3,5,225)= (3^2 ×5^2= 225) \\ \ \\(5,4,260) = (5^2× 4^2= 400) \\ \ \\(1,9,59) = (1^2× 9^2= 162)$$​​
Hence
​$$(3,5,225)= (3^2 ×5^2= 225)$$

Correct answer is (b)​​
