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 1and 3 and then performing mathematical operations on 1 and 3 is NOT allowed)

Show answer & explanation
Correct answer: B
For each set, the third number equals the sum of the squares of the first two numbers. For example, 2^2 + 9^2 = 4 + 81 = 85 and 3^2 + 9^2 = 9 + 81 = 90. In the options, 7^2 + 9^2 = 49 + 81 = 130, so (7, 9, 130) follows the same rule.
